Wizard: I brought the wrong system.

Chapter 104 Detecting Light Sources

Bosco glanced at Yaro's drooping right hand, but didn't pay it any mind. Instead, he asked curiously, "You've finished reading the analysis of basic light magic tricks?"

Why does Wizard Bosco value "Analysis of Basic Light Magic" so much?
Could it be... that I really have a chance?

“Yes,” Yaro nodded in agreement.

"What are your thoughts on the first question at the end of the book?" Bosco put down his pen, crossed his arms, and looked at Yaro with interest.

“The first question is too profound for me to figure out. Why can’t mental energy be attached to a beam of light?” Yaro replied somewhat evasively. He couldn’t talk about photons or wave-particle duality because he couldn’t explain the reasons he knew.

Bosco said nonchalantly, "It's nothing. Just tell me your guess. I just want to take advantage of the active thinking of you young people."

Bosco didn't care about Yaro's arm injury, which could be interpreted as him being used to life and death and getting injured.

However, his attitude toward fluorescent powder was very strange.

Why did he collect it personally yesterday, but today he let the puppet handle it on its own?
Did you deliberately make room for me yesterday so I could see your attitude toward the arrest warrant?
Or is it that his need for fluorescent powder is no longer very high?
These thoughts flashed through Yaro's mind, and upon hearing Bosco's words, he quickly explained:

"Lord Bosco, please don't make things difficult for me. I'm just a novice apprentice, and I don't even understand what mental power is yet. Now you're asking me why mental power can't be attached to a beam of light, and I really can't figure out the reason."

Then, Yaro changed the subject, saying, "I actually have some thoughts on the second question about that book."

"Oh?" Bosco became interested, sat up straight, and looked at Yaro with a serious expression. "Tell me about it."

effective!
Yaro was immediately invigorated and quickly took out the draft paper he had written yesterday.

There are many methods for detecting the speed of light. Although a long time has passed, Yaro still remembers one of them, which relies on changes in starlight.

However, he didn't know much about the stars in this world, so he wrote down two other methods.

Yaro handed over the sketch: "Lord Bosco, please take a look at the sketch I have drawn."

The gear method and the improved octagonal mirror method.

Bosco glanced at the scrap paper, then looked up and asked in confusion, "If the speed of light is so fast, shouldn't it either be visible or invisible forever?"

"The method you wrote probably won't work either, right?"

Yaro stepped closer and pointed to the paper, explaining, "Since you mentioned in the book that the speed of light is finite, but the speed of light is also too fast, it's definitely too late for us to judge it by our own bodies."

"But we can use tools."

"Imagine light as a ball continuously thrown at a wall, and the protrusions of the gears represent the obstruction."

"Only when the rhythm is just right can these balls bounce back."

Bosco was still confused: "That's not right. Gears can block light, but as long as the gears rotate, then we can still see the light afterward, right?"

Yaro pointed in the direction of the light source and explained, "So let the light source and the field of vision use the same gear."

"This ensures that the light source emits light in segments."

"If the rotation speed is not enough, we can always see light, which may be a transition between light and shadow, or it may be flashing."

"But as long as you can still see the light, it means the speed is not fast enough and you need to increase the rotation speed."

"Only when the speed is just right, so that every tooth blocks every piece of light that bounces back."

"At this point, we can calculate the speed of light."

"This way we can avoid the problem of our bodies not being able to keep up with the light."

"What we need to determine is whether the light is blocked."

"If it's not blocked, it means it's not working yet."

“Success is achieved by blocking it.” Bosco listened to Yaro’s explanation, looked at the scrap paper, frowned, and fell into a long silence.

After an unknown amount of time, Bosco suddenly sighed, shook his head, and said, "I still can't understand why this can detect the speed of light."

Yaro understood.

During the exam, if you see the correct answer for a humanities subject, you simply don't want to write it down.

In science, however, even if the correct answer is presented to you, you still won't know it.

I can't figure it out, no matter how hard I try.

Yaro looked up and asked, "Is there anything else you don't understand?"

The less you understand, the smarter I seem, right?

Although I also copied it... after I copied it, I understood, and it seems I'm still better than you.

Bosco, unaware of Yaro's thoughts, simply voiced his doubts: "Your design is indeed ingenious, but if the rotation speed exceeds the speed of light, wouldn't it be useless?"

"You can still see the light, right?"

Yarrow explained, “No, we can observe the degree of brightness.”

"First, we remain still, and the light enters calmly, and we can see the light very clearly."

"Then it starts to rotate, and the light gradually dims."

Yaro turned around and asked, "Is that clear?"

Bosco pondered for a moment, then nodded and said, "Because some of the light was blocked by the gears, right?"

"That's right!"

Yaro nodded in agreement, and seeing Bosco looking at him again, he continued to explain, "We'll gradually speed up, and the light will get dimmer and dimmer, do you understand?"

Bosco: "Because more and more light is being blocked by the gears?"

Seeing that Bosco had finally grasped the point, Yaro breathed a sigh of relief and confirmed, "Yes, that's it!"

Yaro: "Then we observed the light and gradually increased the speed..."

Bosco slammed his fist on the table and exclaimed excitedly, "The light will get dimmer and dimmer!"

You've already learned how to answer first!
pacing back and forth, Bosco clenched his fists and muttered to himself, "As the rotation speed increases, when it reaches a certain limit, all the emitted light will be blocked."

"Knowing the distance light travels and the speed at which the gears rotate, we can calculate the speed of light."

"If the gear speed continues to increase, light will emerge from the next gear gap, and the light we see will gradually become brighter again."

Bosco suddenly looked up, excitedly staring at Yarrow: "A wildly imaginative idea, a brilliant design!"

Yaro quickly replied modestly, "It's all thanks to your books that I've gained inspiration."

I'm sorry, Lord Armand Fiso, I copied your homework.

Bosco asked again, "But what if you can always see the light no matter how you turn it?"

“That means the distance in the middle is still not enough; we haven’t created enough space. As long as the distance is sufficient, we will definitely achieve this effect,” Yaro answered with great certainty.

These are the correct answers that I copied down, but the final test result may not be very accurate.

However, the inevitable phenomena are unavoidable.
