The real yàn made by Wang Yi is the electromagnetic real yàn made by Hertz at the University of Karlsruhe am Rhine in Germany in 1887, and then Wang Yi derives the wavelength of the electromagnetic wave according to the real yàn number jù, and then multiplies it by the frequency of the circuit oscillation, and finally obtains the forward speed of the electromagnetic wave. Exact 300,000 kilometers per second, which is the speed of light. Thus also verifying Maxwell's astonishing prediction that light is only one type of electromagnetic wave.

Subsequently, other researchers in the Dashang Electromagnetic Real Estate Laboratory made persistent efforts to make the reflection, diffraction and interference of electromagnetic waves, and the consistency of electromagnetic waves and light waves was further confirmed. However, the results of this real business have not been announced to the outside world for the time being, and the excitement is only transmitted within the real business room of Dashang Industry. The reason is simple, there is a huge commercial interest behind this discovery, more precisely, Wang Yi wants to win all the patents of radio in the world, including both wireless communication and wireless broadcasting.

Later, it was not only the scholars of the industrial real room who went to visit this miraculous electromagnetic reality, but also the students of the primary school affiliated to Dashang, which was ordered by the king, not to show off, but to let these children have a concept from an early age and understand what scientific reality is. Even if he can't achieve such a goal, as long as he can let them know that there are electromagnetic waves in this world, Wang Yi will be satisfied.

Zhang Jingxiao was sitting opposite Wang Yi at this time, and the young descendant who came with him was sitting next to him. However, Wang Yi is not blind in the TV series, at least he can distinguish between his father and mother, and he really waited until people were bare-chested before he exclaimed, either on purpose, pretending to be stupid, or his own temperament was more alternative. One of the coldest jokes Wang Yi has ever heard about this kind of thing is that Liang Shanbo went to Zhu's house to find Yingtai, but after knowing that Yingtai was a daughter, he vomited blood and died of depression not long after returning home......

Seeing that Wang Yi was always looking at his female companion beside him, Zhang Jingxiao also understood what Wang Yi meant, so he hurriedly introduced: "This is the daughter of my aunt's family, named Qin Luan, dressed like this just for the convenience of travel." ”

"The daughter of your aunt's family, still surnamed Qin...... Uncle Qin? Wang Yi suddenly realized: "Shanxi Qin Wanfeng? ”

"Exactly!"

As soon as Wang Yi mentioned her father's name, the girl immediately glared at Wang Yi.

Wang Yi didn't care, but Shen Yazhi behind him glared back fiercely when he saw righteousness, but he choked Qin Luan, who didn't pay attention.

"Sir, today's reality, I'm afraid it will be able to shake the world, and after those news are transmitted back to Europe and Citigroup, I don't know how to make a sensation." Zhang Jingxiao has taken classes with the literature class, so he is not completely ignorant of electromagnetism.

"I didn't mean to." Wang Yi shook his head and said.

"I wonder why Mr. said that?" Zhang Jingxiao was puzzled, and even Shen Yazhi showed a concerned expression.

"This electromagnetic wave seems simple, but behind it is a huge commercial interest. Whether it is electromagnetic communication or broadcasting, it can be regarded as a product that leads the times. I mentioned all of this when I was teaching you. ”

Zhang Jingxiao nodded.

As soon as he heard that it was for money, Qin Luan sat next to Zhang Jingxiao, and immediately snorted coldly, and said in a low voice: "It smells of copper!" ”

Wang Yi was not polite, and choked back directly, saying, "I said girl, your father is the same as me!" ”

"You!"

"What are you!" Wang Yi glared at each other and said, "Speaking of which, your father and I are also friends of the same generation, in terms of seniority, should you call me uncle!?" Did you talk to your elders like that? ”

Qin Luan's small chest was panting with anger, biting his lower lip angrily, and then turned his face away and stopped talking.

Zhang Jingxiao hurriedly got up, made amends, and said, "Sir, my cousin is rude, I hope Mr. will forgive me." "Wang Yiyi didn't really mean to be embarrassed, he just didn't want this girl to be okay and interjected, so he waved his hand, and it was okay. Zhang Jingxiao wanted to scold a few words, but when he saw the girl's tears around her eyes, she didn't want to say any more heavy words, so she had to divert the topic.

"In that case, why did the gentleman make this fact public?"

Wang Yi smiled at this time and said: "If I, the person who discovered electromagnetic waves, can't make a commercial application of electromagnetic waves, then the relevant patents in this field are snatched by others, don't I deserve it!" Who calls themselves incapable of this! ”

Zhang Jingxiao nodded.

"The world needs China's voice!" Wang Yi looked at Zhang Jingxiao and said earnestly: "We have been blank for too long in the scientific community led by the West, relying on the legacy of our ancestors such as the four great inventions, vainly claiming that we are the kingdom of the Celestial Empire, and we don't know that in the eyes of Westerners, we are just a group of backward barbarians. ”

"It's exactly what the gentleman said!" Zhang Jingxiao sighed.

"But compared to the above two things, I actually value the last point more. I hope that our contribution to electromagnetic waves and the sensational effect it has brought will let the vast number of Chinese young people know that there is still science in this world, and if they can devote themselves to scientific research, it will not matter how great the loss of commercial interests is. Wang Yi paused and continued: "If China wants to become rich and powerful, it is impossible to rely on a big businessman alone. Only by letting the young people of the entire Chinese nation study for the rise of China, and let them understand science and value science, then what country would dare to ride on our heads with a few broken ships and guns to show off its might? ”

Zhang Jingxiao looked moved, got up and bowed deeply to Wang Yi.

Chaowen said, Xi can die, listen to Mr. 's words, let the filial piety suddenly. Mr.'s bosom, my generation is not as good as just in case. ”

Qin Luan sat next to Zhang Jingxiao, although he couldn't understand the conversation between Wang Yi and his cousin, he always had a feeling that they were talking about big things. However, Wang Yi still refused to admit defeat in his heart and said: "After talking for a long time, he is just a man who sells fame and reputation!" ”

It was basically impossible to block the news of electromagnetic waves, and it didn't take long for Wang Yi's name to spread to Europe and to the United States with the telegram!

In the history of the development of modern science, a Chinese name finally appeared!

It didn't take long for scientific research institutions and universities in Europe and the United States to send congratulatory messages to Wang Yi and invite him to come and give lectures at a convenient time.

Of course, Wang Yi does not have this time, and he is now urging the entire electromagnetic laboratory to speed up the commercialization of various functions of electromagnetic waves, especially the research of components represented by electron tubes. Samples of radio communication equipment were estimated to be available by the end of 1876, followed by patent applications and the establishment of factories.

Shen Yazhi was watching Wang Yi have a meeting with a group of foreign researchers, she tilted her little head and listened carefully, although she couldn't understand, she still worked hard.

"Sir, are we now in a position to say that the fluctuations of light are closed?" Emaar Kenny asked slightly excitedly. He is the deputy director of the electromagnetic department of the Dashang Industrial Laboratory, and his status is second only to the group of literary students under Wang Yi. He originally came to Dashang just to support his family, but he suddenly found that God was not thin on him, and he didn't expect that there was such progress in the backward Qing Kingdom.

Of course, on the question of light, everyone present wanted to get a positive answer from Wang Yi, but unfortunately it backfired.

"Come with me!"

There were more than 60 people in the entire electromagnetic room, and everyone followed Wang Yi to the real room on the second floor that verified the storage of electromagnetic waves.

Wang Yi said at this time: "There is no doubt that light is a kind of electromagnetic wave, but there is one thing that is now placed in front of the wave theory...... Light needs to spread in the ether, so which of you can sue me, what is the ether? Has anyone verified his suspension? Or rather, is the ether really in existence? ”

If Wang Yi's electromagnetic wave experiment is an obedience and verification of Maxwell's classical theory, then his suspicion of the existence of the ether is completely deviant.

Everyone looked at Wang Yi in shock, except for the only eight literary students in the room.

"Sir, do you think that the aether does not exist zài?" A young scholar asked in a low voice.

Wang Yi looked at everyone present and said with a smile: "Now no one can find evidence of the existence of the ether, and anyone's explanation of the ether is far-fetched. Don't you think that there is a more plausible explanation than those far-fetched!? ”

What is this explanation...... Everyone present knew it in their hearts.

Wang Yi continued: "Just as people used to think that the so-called phlogiston would be consumed when burning, everyone firmly believed that the so-called phlogiston existed. But does it really exist? Don't you think that today's ether has much in common with the phlogiston of the past? ”

Everyone fell into deep thought, they felt that Wang Yi's voice had a kind of deafening magic, and they who were still cheering for the fluctuations just now, suddenly found that there had been a wall in front of them, which could not be crossed.

"Sir, since we have proved that light is a type of electromagnetic wave, can we still deny the existence of the ether?" Emaar Kendi's statement is also reasonable.

"Oh, Mr. Kendi, you're stealing concepts. Light is a type of electromagnetic wave, so why does the ether have to be zài? ”

People all looked at Wang Yi in surprise, "Is there no medium, and waves can still spread?" ”

Wang smiled and said nothing, and it took a long time before he said: "Change the topic, just now I brought everyone to this real room to let everyone see a phenomenon. ”

Then he began to move, and under the curious and slightly excited gaze of the people, he made a small hole in the closed black curtain, and a beam of light came in, which happened to shine through the gap in the brass ring. Later, he did a comparative test, what is the difference between electromagnetic waves in the presence of light and the absence of light?

After measurements, people were surprised to find that the generation of electric sparks seemed to be easier under the conditions of light exposure.

No one could explain the reason for the existence of this phenomenon, and when they wanted to ask Wang Yi about the reason, Wang Yi smiled and said, "After completing the task I assigned to you, you can try to think about this phenomenon in your spare time." Believe me, there's a new chapter in physics. ”
