Although Glenn's beam measurement experiment ultimately failed miserably, it pushed wizards' curiosity about the speed of light to another climax.
Because the results of the experiment shocked them so much, every wizard talked about the terrifying power of condensing strong light into a beam.
It is foreseeable that optics will become the research direction of many wizards in the future.
However, when it comes to measuring the speed of light, wizards are divided into two camps. Some people insist that the speed of light is infinite. After all, they can see the sun and moon which are extremely far away from here at a glance.
Measuring the speed of light is nonsense!
Others believe that the speed of light is limited because everything has that limit, and the 'light element' is no exception, but they don't think they should continue the experiment like this.
For light, even a distance of one hundred kilometers is a blink of an eye. If this thing has a speed, it must exceed 10,000 kilometers per second to be so fast that no one can react. You must know that this thing is under their feet. The circumference of the Eternal Star is only over 40,000 kilometers!
"Is it possible to carry out experiments at both ends of the planet?" This idea came to Sanchez's mind. The venue would be big enough, so how would they get there?
"Idiot, this planet is round, and light travels in a straight line. It is either blocked or flies into the universe, but cannot reach the other side." Raphael said with a sneer.
"Then what else can you do?" Sanchez asked angrily.
Raphael opened his mouth, then shook his head helplessly. "How do I know this?"
This magic star has so many ideas. Who would have thought before last year's magic seminar that he could calculate the circumference of the entire planet just by setting up an icicle on the sea and measuring the length of the shadow? Length and volume...
So Raphael couldn't guess what new ideas the other party could come up with this time...
Out of curiosity, this magic seminar will continue. After three days, a total of three recipients of the Morning Star Medal appeared.
They are Glenn, who created the light-gathering magic, Fulla, who took the stage to explain the theory of electromagnetism on behalf of Anthony, and...
Yolande, who made a crude microscope... This wizard of the prophecy school was speechless after being refuted by Linn at last year's seminar. He learned from the experience and devoted himself wholeheartedly to research.
When using an astronomical telescope to observe distant stars, Yolande suddenly had the idea to make some improvements to this thing, and successfully built a microscope.
Although the two had a tit-for-tat confrontation at the seminar a year ago, Lin En did not take this small conflict to heart. It was nothing more than an academic dispute. No matter how fierce the quarrel was, it was normal, and the other party did not deliberately engage in any despicable behavior. In order to disgust himself, Lin En generously nominated Yolande for the Morning Star Medal.
This kind of generosity made Yolande feel ashamed.
He was already prepared to be targeted this time, and even wrote a speech of tens of thousands of words in advance to explain the importance of this research. However, he did not expect that it would not be used at all. Instead, Lin En was the first to propose it to him. The adjudicator who hands out the Medal of the Morning Star.
In the past few days of working together, Rafael kept making insinuations, hoping that Linn could reveal some details, but he was blocked by the latter... He could only mutter secretly, could it be Sanchez's guess? That's right, the magic star wasn't completely sure about the experiment, so he kept it secretive.
Linn ignored all the rumors spreading wildly in the Wizarding Land. After returning to the lounge of the Iyetta School, he called Alok and others over and asked about their preparations.
"Dean Linn, you asked us to get the gears ready!" Alok and Peirce said tiredly.
It took them three days to make ten gears of the same size, ranging from five hundred to one thousand two hundred teeth. According to the dean's instructions, the accuracy must be ensured, and the distance between each tooth gap is exactly the same. , the accuracy can reach one thousandth of a centimeter.
Only formal wizards can do such delicate work, which is why Linn brought them here specially - after all, someone has to be responsible for the work!
Lydia and Jonny are responsible for the production of semi-transparent mirrors and reflectors, which are now completed.
"Very good, it seems we can start the experiment tonight!" Lin En checked the various experimental supplies and nodded with satisfaction.
Elok and others were extremely surprised. Why did the dean ask them to make so many gears?
"Do we have to rely on these things to measure the speed of light?" Lydia raised her hand and asked.
"Yes, the gears are enough!" Linn nodded.
…
At night, in Greenriel City, wizards who had received the news and came to watch the experiment crowded the entire square.
With the name of Magic Star and the experiment of measuring the speed of light, no one wants to miss this grand occasion.
"Master Lin En, we have been waiting for several days. You are not going to show off now, are you?" Raphael said helplessly. He has been thinking about what other methods he can use in the past few days. I conducted an experiment, but as a result, I ran out of ideas and didn't have any ideas.
"My method is very simple, and everything you need is here!" Linn said with a smile.
Raphael and others curiously looked at the experimental equipment in front of Lin En. The most conspicuous thing was naturally the strange-looking alchemical instrument. After Lin En's explanation, they understood that this thing was used to emit light beams. The principle was the same. Glenn's focus magic is about the same.
A reflector is placed on the city wall of the DC area, exactly four kilometers away from this square...
"Isn't this the same reflector Glenn made a few days ago to measure the speed of light?"
Nancy murmured softly, and the wizards present nodded in unison.
You must know that Glenn used a hundred mirrors to create a range of one hundred kilometers, but in the end it still ended in failure. Although the mirror set up by Linn passed through most of Greenriel City, even including the round trip The distance is only eight kilometers, less than one-tenth.
Measuring the speed of light is simply impossible!
"So we need to add this!" Linn pointed at what Elok was holding. "This is the most critical part of this experiment!"
"Gears?" Raphael recognized it at a glance. This thing was no stranger to alchemists. It existed in the steam engines built by the Alchemy Society before.
What does this have to do with the measurement of the speed of light?
