When using the octagonal mirror method to measure the speed of light, the most important values to know are the distance between the rotating mirror and the reflection point, and the other is the rotational speed of the rotating roulette when the light is successfully reflected again.
The reason why the light sources need to be further apart is to prevent the light released by the light source from directly illuminating multiple mirrors.
The reason why the observation points need to be further apart is to increase the accuracy. The farther the observation points are, the more accurate the final measured data will be.
Because of this, the light source and the observation point do not need to know the specific distance, as long as they are on the same horizontal line.
Yaro squatted down, looked at the refracted light through the gap between the stones, and then put a piece of magic stone into the silver card slot extending from the rotation speed wheel.
Buzz!
As the magic power poured in, the eight-sided mirror began to rotate gradually.
Such a slow speed, relative to the speed of light, is almost the same as a stationary state.
Therefore, Yaro could see the light again and again through the observation point.
This is the possible scenario in Bosco's imagination, and since this situation will occur in a low speed state, isn't it also the same when it is in a fast state?
The rotating roulette wheel in the middle rotates back and forth, and the light sways randomly. There will always be a few rays of light that happen to shine at the observation point, right?
Bosco admitted that the principle explained by Yarrow was indeed very reasonable in theory, but he still could not overcome his own common sense. He always used common sense to bring common sense into thinking, and the result of thinking with common sense was that Yarrow's experiment Unable to succeed.
These two contradictory conclusions have always puzzled him and have almost become a problem for him.
After seeing what he had imagined, Bosco crossed his arms and watched Yaro's expression with great interest, hoping to see tension on Yaro's face.
He not only hopes that Yaro will succeed, but also looks forward to Yaro's failure to prove that his guess is correct.
"If Yaro fails, how will I comfort him later?"
Although he didn't want this to be the result, he couldn't help but think so wildly, and used facts to prove that his long life was not wasted.
As for Olive?
Who has time for him?
Olive stood quietly aside, his eyes rolling, thinking about what reasons and excuses he would use later to get through.
Digging a grave in front of the college is definitely not something that can be explained honestly.
Yaro didn't know what Olive was thinking, let alone Bosco, who hadn't figured out the reason until now, and was still expecting his own failure.
He just calmly input magic power into the card slot and gradually accelerated the speed of the eight-sided mirror in the middle.
not enough!
As the eight-sided mirror rotated faster and faster, the reflected light shone randomly from the top of the mountain, illuminating the towering giant trees behind them.
Just like a rotating electric fan, the actual blades cannot be seen. When the speed reaches a certain level, the dot-like spots gradually become broken lines.
Not enough, not enough!
The rotation speed of the rotating compass continued to accelerate, and the broken rays of light slowly extended and gradually healed each other.
Faster, faster!
Finally, the broken rays of light were connected together, and no trace of light spots could be seen anymore. The overall brightness of the space behind the few people increased a little.
Bosco looked at the tall and bright trees, and finally couldn't help but said: "Yaro, forget it if you can't do it, I won't blame you."
Bosco thought that Yaro had been trying to be brave and that Yaro was worried about his blame, so he comforted him: "I have said before that your first gear plan has the best chance of success."
Even if both methods fail, Bosco will not be able to take back what he gave away, which means that the original 'sunk costs' will not disappear, and Bosco's attitude towards Yaro will not change.
Bosco never said that he would not be rewarded until Yarrow succeeded.
The reason why he gave those things away was because of Yaro's way of thinking and Yaro's powerful talent for learning spells.
The failure of several separate experiments only shows that there are still some undiscovered properties in the light. As long as you have strong thinking ability and adjust the experimental plan, you may be able to truly discover a 'new path'.
And the 'new road' is the most worth pursuing!
"Teacher, what are you talking about?" Yaro looked up in surprise.
Could it be that you can only figure out the principle of the gear method and still haven't understood the principle of the 'octagonal mirror method'?
No way?
You are an old wizard who wrote a book and put it in the library!
Is your thinking ability so poor?
As if he understood the meaning in Yaro's eyes, Bosco coughed a few times, felt a little embarrassed, and deliberately looked around and said, "Why hasn't your experiment been successful?"
Yaro looked at Bosco with a strange look, pointed to the back and said: "Teacher, you can see that the back is getting brighter and brighter, which means it is about to succeed."
The rear is getting brighter and brighter, which means that more and more light is passing through the reflection point, and the speed at this time is approaching the real demand.
"Yeah?"
Bosco looked at the light behind him in confusion, still feeling vaguely understanding, but for the sake of his dignity as a 'teacher', he pretended to be satisfied, stroked his beard and praised: "Okay, very good, then Just keep going!”
Forehead……
You usually don't touch your beard, but if you do this now, doesn't it mean that you have a guilty conscience?
But in order to maintain the teacher's dignity, Yaro pretended to be ignorant and bowed his head and continued his experiment.
When the eight-sided mirror rotates, it is inevitable to lose a large amount of light, so the final reflected light beam will be much weaker than the static state. Yaro must pay attention to this and seize the moment when the light appears.
Fortunately, there are many towering "sound-absorbing balsa" behind Yarrow. These "sound-absorbing balsa" will serve as background walls and provide important reminders for the last critical time.
Speed up, speed up!
"Woooooooo..."
The eight-sided mirror in the center rotated faster and faster, blowing the cool night wind. Yaro raised his head from time to time, staring back and forth at the giant tree behind him and the observation point in front of him.
Suddenly, Yaro's eyes lit up and he looked at a spot of light that suddenly appeared behind him.
"Appeared!"
That light spot is the total convergence of light points reflected by eight identical planes. When the light points always spit out at one location, a light spot that is much brighter than the surroundings will naturally appear at that location.
Add a little more, add a little more...
Yaro did not dare to relax and carefully added magic power to the silver card slot in his hand, making subtle adjustments to accelerate it weakly.
As the process progressed, the light spot gradually moved. Yaro quickly lowered his head and stared at the rotating eight-sided mirror from the observation point.
Uh-huh!
Swish!
Suddenly, light broke through the darkness, and through the narrow field of view of the observation point, it came into Yaro's eyes.
"Appeared!"
"Success!"
