Wizard: I brought the wrong system.

Chapter 135 Conducting Experiments
When determining the speed of light using the octahedral mirror method, the most important values ​​to know are the distance between the rotating mirror and the reflection point, and the rotational speed of the rotating disk when the light is successfully reflected again.

The reason for keeping the light sources apart is to prevent the light emitted by the light sources from directly illuminating multiple mirrors.

The reason for keeping the observation points far apart is to increase accuracy; the farther apart the observation points are, the more accurate the final measured data will be.

Therefore, the exact distance between the light source and the observation point does not need to be known.

Yaro crouched down, looked through the cracks in the rocks at the refracted light, and then placed a magic stone into the silver slot that extended from the rotating wheel.

hum!
As magic was poured in, the octagonal mirror began to rotate gradually.

Such a slow speed is almost equivalent to being at rest relative to the speed of light.

Therefore, through the observation point, Yarrow could see the light again and again.

This is the scenario that Bosco envisions. And since this situation occurs at low speeds, wouldn't it be the same at high speeds?

As the central rotating wheel spins back and forth, and the randomly swaying light beams, surely a few beams will happen to shine on the observation point?
Bosco acknowledged that the principle explained by Yarrow was indeed theoretically reasonable, but he still couldn't overcome his own common sense and always tended to bring common sense into his thinking. The result of bringing common sense into his thinking was that Yarrow's experiment could not succeed.

These two contradictory conclusions had been perplexing him and were almost becoming a source of anxiety for him.

After seeing it, the scene I had imagined indeed appeared.

Bosco stood with his arms crossed, watching Yaro's expression with great interest, hoping to see nervousness on Yaro's face.

He hoped that Yarrow would succeed.

They also hoped for Yarrow's defeat, to prove that their conjecture was correct.

"If Yaro fails, how will I comfort him?"

Although he didn't want it to end this way, he couldn't help but imagine it and use the facts to prove that his long life had not been wasted.

As for Oliver?
Who has time to deal with him?

Oliver stood quietly to the side, his eyes darting around as he pondered what reason or excuse he could use to get away with it.

I certainly can't honestly confess to digging up graves in front of the college.

Yaro was unaware of Olive's thoughts, let alone Bosco's, and still hadn't grasped the underlying principles, even anticipating his own failure.

He calmly channeled magic into the card slot, gradually increasing the rotation speed of the central octagonal mirror.

not enough!

As the octagonal mirror spun faster and faster, the reflected light shone haphazardly from the mountaintop, illuminating the towering trees behind them.

Just like a rotating electric fan, you can't see the actual blades. But once the speed reaches a certain level, the light spots that were originally dots gradually connect into broken lines.

Not enough, not enough!

The rotating compass continued to spin faster, and the broken rays of light slowly extended, gradually healing each other.

Faster, faster!
Finally, the broken rays of light reconnected, and no trace of the light spots could be seen anymore. The overall brightness of the space behind them increased slightly.

Looking at the towering, gleaming tree, Bosco finally couldn't help but speak up: "Yaro, if it can't be done, so be it. I won't blame you."

Bosco thought that Yaro was just putting on a brave face and that Yaro was worried about being blamed, so he comforted him, saying, "I told you long ago that your first gear design had the best chance of success."

Even if both methods fail, Bosco cannot take back what he has given away. In other words, the existing 'sunk costs' will not disappear, and Bosco's attitude towards Jaro will not change.

Bosco never said that the reward would only be given after Yaro succeeded. The reason he gave those things away was because he valued Yaro's way of thinking and his strong talent for learning magic.

The failure of a few experiments only indicates that there are still some undiscovered properties in light. With strong thinking ability, and by adjusting the experimental plan, we may be able to discover a 'new path'.

But the 'new path' is what's most worth pursuing!
"Teacher, what are you saying?" Yaro looked up in surprise.

Is it possible that you can only understand the principle of the gear method, but still don't understand the principle of the 'eight-faced mirror method'?

No way?
You're the old wizard who wrote books and put them in the library!

Is their thinking ability really that bad?
Seemingly understanding the meaning in Yaro's eyes, Bosco coughed a few times, slightly embarrassed, and deliberately looked around, saying, "Why hasn't your experiment succeeded yet?"

Yaro looked at Bosco with a strange expression and pointed behind him, saying, "Mentor, look, it's getting brighter and brighter behind us. That means we're about to succeed."

The light behind is getting brighter, which means that more and more light is passing through the reflection point, and the speed is approaching the actual requirement.

"is it?"

Bosco looked at the light behind him with a puzzled expression, still feeling a sense of not quite understanding. But to maintain his dignity as a 'teacher,' he feigned satisfaction, stroked his beard, and praised, "Good, very good, then continue!"

amount……

You don't usually touch your beard, so isn't this gesture a sign that you're feeling guilty?

But to maintain his teacher's dignity, Yarrow pretended not to know and lowered his head, continuing his experiment.

As the octagonal mirror rotates, the loss of a large amount of light is unavoidable. Therefore, the final reflected beam will be much weaker than when it is stationary. Yarrow must pay attention to this and seize the moment when the light appears.

Fortunately, there were many towering balsa woods behind Yaro, which would act as a backdrop, providing an important reminder for the final crucial moment.

Speed ​​up, speed up!
"Woooooooo..."

The octagonal mirror in the center rotated faster and faster, blowing in gusts of cool night wind. Yaro would occasionally look up, looking back and forth between the giant tree behind him and the observation point in front of him.

Suddenly, Yaro's eyes lit up as he looked at a spot of light that had suddenly appeared behind him.

"Appeared!"

That spot of light is formed by the convergence of light points reflected from eight identical planes. When the light points are always emitted towards one location, a spot of light that is much brighter than the surrounding area will naturally appear at that location.

Just a little bit more, just a little bit more...

Yaro dared not relax, carefully adding magic to the silver card slot in his hand, making subtle adjustments to slightly accelerate it.

As this process continued, the spot of light gradually moved, and Yaro quickly lowered his head, staring intently at the rotating octagonal mirror from his observation point.

Swish!
Swish!

Suddenly, light pierced the darkness and entered Yaro's eyes through the narrow field of vision of the observation point.

"Appeared!"

"Success!"

Yesterday, in order to finish the third watch, I went to bed too late, and today I'm only getting one update so far.
