After Linn announced the end of the seminar, the wizards who walked out of the exhibition hall still could not recover from the dispute between light waves and light particle theory.
"Do you really think that wave properties and particle properties can exist at the same time?" "This is simply nonsense. How is it possible that something is both continuous and dispersed?"
"This is coming from the mouth of Speaker Lin En, the Magic Star. If he is not completely sure, who would destroy his reputation in a seminar with tens of thousands of people?" Raphael interrupted everyone's debate. He said this The research on this magic star is very trustworthy.
"So what if it's a magic star? Doesn't it make mistakes if it's famous?" A great wizard from the empire sneered and said, as long as it is an individual, there will be some negligence.
It has only been more than a year since the establishment of optics, and no one dares to say that they can completely understand it.
Compared to the arguments between ordinary wizards, Anthony looked at the disclaimer in his hand and remained silent for a long time.
The above content is very brief. It means that those who sign the agreement are voluntarily responsible for all the consequences of listening to quantum theory, but... the meaning behind this is chilling.
"Teacher, should we sign or not?" Fulla asked hesitantly, with a slightly worried look on her face.
She did not have the same firm belief as Anthony, so she had long lost the ability to sense electric charges. She had a deep understanding of [Spellcasting Obstacles], and she couldn't help but feel a little withdrawn in her heart.
"Sign, of course you have to sign!" Anthony said without hesitation.
He believed that his research was absolutely correct. Light is a wave, and it is an electromagnetic wave!
Anthony's fingertips lit up with magic fluorescence, and he signed the disclaimer with ink, then handed it to Fulla and asked her to give it to Linn.
"Yes, teacher!" Seeing that Anthony had made up his mind, Fulla said no more, signed her own disclaimer, and then returned to the exhibition hall with the two statements.
After Furla left, Anthony closed his eyes. After about two or three seconds, he suddenly breathed a sigh of relief and relaxed a lot... He could still use the thunder and lightning spell, which was good, very good!
On the other side, Fulla, who came to see Speaker Lin En, hit a wall because there were so many people who wanted to find the magic star.
There are people like Raphael and others who have good connections and came here to discuss the theory of photoelectricity. There are also some wizards who have prepared generous gifts and plan to have a relationship with the new speaker. Plus they come to submit the disclaimer, and it is simply a mess!
Lin En is worrying about how to emit a single particle. Of course, he will not spend his time and energy here at this time. He will close the door in the name of manufacturing experimental equipment.
Even the requests from several speakers were no exception - Linn simply gave them a few research manuscripts to get rid of the problem.
Micro and macro are completely two sets of theories. It is not only time-consuming and laborious to explain them one by one, but the other party may not be able to understand them. It is better to wait until tomorrow's academic seminar to explain them together to avoid having to explain them several times.
Jonny and Alok stood guard at the door, apologetically informing everyone who wanted to see them that Speaker Lynn was preparing for tomorrow's seminar and accepted the disclaimer they brought.
The two people's efforts also allowed Lin En, who was in the room, to relax and start thinking about how to emit particles.
His initial goal was to use alchemy to replicate the Federation's particle extraction device, but it took him half a month to discover that the device was too difficult. Even if he could now achieve atomic-level control, he still couldn't do it.
But it’s normal to think about it. In addition to using a strong magnetic field, this thing also uses quantum technology...
So Linn could only consider some relatively old methods - such as thermal field emission electron guns!
…
The night passed by in a blink of an eye.
It's just that this night was not peaceful, and not many people could sleep well.
Fortunately, as a wizard, staying up late is nothing. Sometimes it is normal to work hard for several days in order to study a technique. Almost as early as the next morning, the large exhibition hall was already full of people.
Anthony had also arrived, and his eyes swept across the rows of large exhibition halls. Only about 30% of the seats were empty. It seemed that not many people were scared away by the disclaimer.
But yes, the debate about the nature of light will come to a conclusion today. As long as wizards still have the idea of knowing, they will never miss this opportunity.
As for those who shrink back, Anthony is very disdainful. They have lost their belief in seeking the truth and are afraid that their path to magic will come to an end!
At about eight o'clock in the morning, all the speakers had arrived, and Linn was no exception. He also asked Alok and others to carry out his experimental device.
"Isn't that my double-slit interference experiment?" Jeffrey said in surprise.
Anthony and others also recognized it, after all, the two were so similar.
They are all emitting devices on the left, with a partition in the middle and a photosensitive screen on the right.
Under everyone's discussion, Lin En also nodded. "Yes, this is exactly the double-slit interference experiment. To be precise, I have modified it to some extent!"
"The device on the left, I call it the thermal field emission electron gun, consists of five parts: filament, cathode, grid, anode, and deflection coil..."
With a wave of his hand, Linn split the outer casing with great precision without damaging the internal structure. Then he explained its working principle to everyone.
The so-called filament is not the hair of a fire lion, but a tungsten filament. When it is energized, it converts electrical energy into thermal energy and heats the cathode, thereby releasing and emitting a large number of electrons.
These electrons will be blocked by the grid. By adjusting its relative position to the cathode, the amount of electron beam passing through can be controlled. Finally, they are accelerated under the electric field generated by the anode, and the orientation is adjusted by the deflection coil, and finally the electrons are emitted one by one.
Lin En's explanation was very professional. Many of the nouns were confused by the wizards present. Fortunately, they understood the last part. The magic star found a way to emit a single electron and prepared to use it. to conduct experiments.
"But... shouldn't it be photons?" A young witch whispered.
The voice was very soft, but none of the wizards present had clear ears and eyesight.
Lin En rolled his eyes. Emitting a single photon was more troublesome than electrons.
"It's okay, it's all the same!" Lin En said with a smile. They are both microscopic particles and have quantum phenomena.
After Lin En explained something, he stopped talking and looked at everyone and spoke again. "My experiment is very simple. I use an electron gun to shoot electrons into the double slits one by one, and then observe their distribution image through the special fluorescent screen behind..."
"What do you think will happen if particles pass through the double slits?" Linn suddenly asked.
The wizards present pondered for a while and quickly came to a conclusion. Glenn was the first to speak out. "It should be like a small hole imaging, and the corresponding image should be mapped on the back!"
"Then give it a try!" Linn did not agree or reject Glenn's words, and directly started the thermal field emission electron gun. Under the attention of everyone, the tungsten wire lit up when heated...
In the invisible microscopic realm, one after another accelerated electrons hit the front at extremely fast speeds.
Since the holes are very small, it is not easy to pass through them, so most of these electrons hit the partition.
After waiting like this for about five seconds, Harrov said solemnly. "It's gone!"
Arad and the others stared at the photosensitive screen behind the partition with their eyes widened, and then they realized that a tiny dot suddenly lit up.
This means that Lynn's thermal field emission electron gun successfully shot a single electron onto the special photosensitive screen at the rear.
As time goes by, the light spots on the photosensitive screen become more and more dense, but it is not the reflection of two gaps as they imagined, the light spots are roughly distributed in nine Within a strip-shaped area... although there are light spots in the rest of the area, the number is very small.
"This...is this an interference stripe?!" Anthony looked at the scene in front of him with a look of astonishment on his face.
The rest of the wizards were equally incredible. Even the great wizards in the front row couldn't help but took a few steps closer to confirm at close range that this was not an illusion and that there was nothing wrong with their eyes.
"Strange, why is this happening?" Vittorio frowned and muttered to himself.
"Hahaha, light particles are right, my light particle theory is right!" Sanchez shouted with great excitement, which shows that particles can also produce fluctuations!
"Idiot!" Anthony interrupted Sanchez directly. "If electrons really pass through the holes one by one, what affects their trajectory?"
Sanchez's laughter stopped suddenly, and he was obviously aware of this. His previous particle scattering experiment was successful because he relied on his numerical advantage to simulate the collision of particles in two exploding element clusters. Fluctuating path.
The current situation is different. The electrons pass through the gaps one by one, and normally they will not be affected by any interference. However, the fact is that these electrons have deviated from their original direction.
It is as if there is a mysterious force that causes these electrons to fall to these fixed points in a wave path.
A chill ran down Sanchez's back as he wondered what was affecting these microscopic particles.
"Is there something wrong with the electron gun? In fact, the electrons emitted at a time are not just one, but many..." A great wizard suddenly thought of this, but under the gaze of a group of wizards, his voice became louder and louder. It got smaller and smaller, and then it stopped directly.
After all, this was an experiment to question the magic star in person.
However, soon people seemed to think that it was indeed an explanation method, assuming that many electrons passed through the holes, and then they affected each other.
Although such a guess is outrageous, it cannot explain why the light spots on the photosensitive screen only light up one by one, and why the electrons happen to be on the same path as the wave trajectory, but it is still an explanation.
"Since everyone has doubts, why don't you all enter the magic network, and I will take you to 'take a look' for yourself?" Lin En said with a smile, and then he connected the recently developed The spell of the magic net was announced.
This is a very simple psychic magic, not very difficult, and anyone at the level of a formal wizard can use it.
In just a few minutes, the wizard in the exhibition hall had mastered this magic.
Zhinao's reminder sounded loudly in his mind, and more and more people were connecting to the magic network.
Even though most of the wizards had just connected to the Magic Network and had very little computing power to mobilize, they still couldn't handle the large number of people and still managed to 'support' Lin En...
The level of mental power has also been raised from seven to eight.
His soul strength cannot keep up with the rapid growth of computing power.
Lin En spent ten seconds to adapt, and then expanded his domain to include the entire large exhibition hall. Under the link of the magic network, all wizards present temporarily gained the ability to perceive electromagnetic fields.
At the same time, within a tenth of a second, the thermal field emission electron gun fired another electron.
Glenn, who was staring closely at the experiment in the front row, instantly sensed the disturbance of the electromagnetic field. This disturbance was very small, but under the huge computing power provided by the magic network, it was extremely clear.
This 'electron' was very lucky to pass through the gap on the right and hit the photosensitive screen. A subtle light spot also lit up at the corresponding position on the screen.
"Really, there is really only one electron!" Anthony was extremely confused. Although they did not actually see or sense the electron itself, they could observe the general trajectory through the disturbance caused by this thing.
The particles indeed travel in straight lines, and the light spots that light up on the rear photosensitive screen are solid evidence.
But why do there appear those weird interference fringes similar to those caused by waves?
The wizards who were as puzzled by this as Anthony were all 120% more energetic. They wanted to see with their own eyes what exactly affected the trajectory of electrons.
The thermal field emission electron gun fired non-stop. Under the "close gaze" of Anthony and others, every lucky "electron" passed through one of the gaps without any change in the path.
What about the promised deflection?
If this continues, how are light spots similar to interference fringes formed?
Anthony's expression became more and more confused, and at this moment, a burst of exclamations suddenly sounded in the exhibition hall.
"Look, the photosensitive screen... the photosensitive screen... has changed!"
Anthony's pupils tightened, and he noticed that at some point, the pattern on the screen had gradually changed from nine stripes to two...
Seeing such a scene, even Harrov, Vittorio and Aurora couldn't sit still. Their six eyes were fixed on the changing photosensitive screen, and then they turned to sit quietly at the judging table. of lynn.
Linn shrugged and said very calmly. "You have also seen that my electronic launch gun is placed there, and no one has touched it!"
