Text Chapter 59 Reading Comprehension

"This book..."

Baili Qingfeng flipped through these books.

Force, several common forces, synthesis of force, decomposition of force...

"It's not about electromagnetic knowledge, but I can't be biased... Otherwise, it will definitely affect the final grade. Even if the knowledge is not what I want, I have to endure it."

Baili Qingfeng pursed his lips and continued to browse.

Interaction of forces, friction, static friction, coefficient of friction, resultant force, centrifugal force, vibration and resonance...

"This is a bit interesting."

Seeing this, Baili Qingfeng stopped suddenly as if chewing chicken ribs.

At the beginning of the nineteenth century, when an army marching in uniform steps passed a stone bridge, it trampled down a bridge through the principle of resonance.

"Amplitude, period, frequency, natural frequency...resonance..."

Baili Qingfeng looked at the description in the book.

A woman in the country played the flute, but the caterpillars on the fruit tree died one after another. It was because the sound of the flute transmitted the vibration to the caterpillars through the air, causing the caterpillars to vibrate forcedly. Because the frequencies of the two were similar, the internal organs of the caterpillars resonated. Rupture leads to death.

"If you can study this, maybe you can create a boxing technique or a secret method, which can cause the internal organs of others to resonate with vibration waves, and tear their internal organs apart."

Baili Qingfeng also has a good physical foundation. To create a secret method based on the principle of resonance, one must understand vibration waves.

There are many types of vibration waves, not to mention the basic ones of transverse waves and longitudinal waves, but also the period, wavelength, and wave velocity of the waves. The relationship between the three can be expressed by υ=λ/T.

This simple formula applies to both electromagnetic waves and light waves.

After watching some waves, Baili Qingfeng quickly saw something else of interest.

sound waves.

Most media in the world can transmit sound waves, but different media transmit at different speeds.

For example, the sound speed of air is 332 meters per second, that of water reaches 1450, that of copper reaches 3800, and that of iron reaches 4900. However, the reason why Baili Qingfeng is interested in these is that sound waves Vibration rules.

Vibration with rules and periods can be called music, which is peaceful and pleasant to the ear, while vibrations without rules and periods can only be noise, which makes people crazy.

But this statement cannot be summed up in one sentence.

After all, there are three elements of music: pitch, loudness, and timbre.

"Sure enough, people who love music should learn more about physics, so that they can see the essence of music clearly."

Baili Qingfeng finally started to read this textbook with relish gradually.

A brand new door is slowly opening to him.

...

Shuiyun elegant rhyme.

After a week, Baili Qingfeng came to this musical instrument store again.

This time, there were no other guests on the second floor except Gu Lingying, Qin Lanshan, and Yun Shengyan.

"Brother Qingfeng, you're here."

Seeing Baili Qingfeng, Qin Lanshan was the first to go up to him: "My dad thought you are very talented after listening to your music, he wants to meet you, I wonder if it's okay?"

Baili Qingfeng thought for a while, and agreed: "Yes, let's stay here next time."

"Okay then, little brother Qingfeng, we've settled for that."

Qin Lanshan said happily.

"Senior Qingfeng, what do you think of pop music?"

Gu Lingying asked with a smile.

She is wearing an antique dress today, with a white wing hair clip on her head, her soft hair falls naturally on her shoulders, and a sky blue belt is tied around her slender waist, looking pure and elegant.

"Actually, I think there is no need to distinguish between pop music, classical music, electronic music, and dance drama music. As long as it sounds good and touches people's hearts, it is good music."

Baili Qingfeng said.

"Yes, as long as it sounds good, regardless of genre, I like to listen to it."

Qin Lanshan said with a smile.

Next, listen to songs, play the piano, blow the flute, chat, and discuss some related knowledge. The day passed quickly.

When it was time to say goodbye, Gu Lingying glanced at Baili Qingfeng, as if he was hesitant to say anything.

After a while, she stepped forward and said, "Senior Qingfeng, I would like to ask you to do me a favor. I wonder if you have heard of the music program 'Tian Lai'."

"TV music show..."

Baili Qingfeng thought about it carefully: "The last time I watched TV... seemed to be a few months ago, and the news was playing at home..."

Qin Lanshan on the side was stunned, a little unbelievable: "Brother Qingfeng, 'Tian Lai' is the best and most popular music program in the whole of Xia, and you, an industry insider, don't know?"

"An insider? Singing is just my hobby, I'm not an insider."

Baili Qingfeng said honestly: "As a student, I spend most of my time reading and studying."

"..."

Qin Lanshan heard Baili Qingfeng's reason, but she didn't know how to refute it.

Students, really should study hard.

"But if you have anything to say, I'll see if I can help."

"It's like this. One of my senior sisters, Su Weiwei, was supposed to be number one in 'Tian Lai', but she only got fourth because of internal operations, and she didn't make it into the top three. She plans to hold a small pop concert to prove herself. After learning about this, the teacher gave great support and recommended the two of us to be guests, performing Swordsman and Heaven and Earth Cooperation, but... I don’t know if Senior Qingfeng has time.”

"I'm just an amateur music lover, this kind of occasion will definitely be nervous, forget it."

Baili Qingfeng said.

"Like This……"

Gu Lingying was a little lonely.

But Qin Lanshan came up close, and said pitifully, "Brother Qingfeng, just promise to help sister Weiwei, you don't know, that issue of 'Sounds of Nature' doesn't matter if it's first, second or third. They are far from being the opponent of Sister Weiwei, but relying on internal operations, they eliminated Sister Weiwei's first place, which is really annoying. It’s not a concert, there aren’t many people, the invited audience is less than 200 people, most of them are well-known people in the industry, they are all people who love music and understand music, you definitely have something in common.”

Yun Shengyan at the side thought for a moment, and then said: "That girl Weiwei is indeed very talented, it would be a pity if she fell into a slump after being suppressed like this."

Baili Qingfeng glanced at the three of them, and finally paused for a moment on Gu Lingying, hesitantly said: "According to what you said, this is the battle of your senior sister Su, if I don't perform well... ..."

"Senior Qingfeng, I believe in your level."

Gu Lingying looked at Baili Qingfeng, full of trust.

"That's right, little brother Qingfeng, you can do it."

Qin Lanshan clenched her fist and encouraged her.

"Well."

Baili Qingfeng responded, and said to Gu Lingying, "Then let's work hard together."

"Yes, let's work together, we can practice more when we have time."

"Speaking of practice, I have gained some new understanding of music recently, and discovered a lot of new knowledge. These knowledge are precious, but I am still recording them. I will give them to you when I finish the recording. look."

Baili Qingfeng said.

"Wow? What kind of music cheats? You can become a music master after reading it? I really want to read it now."

Qin Lanshan quickly approached her, bringing a burst of girlish fragrance.

Not only Qin Lanshan, but also Gu Lingying and Yun Shengyan rushed forward.

And Baili Qingfeng didn't hide anything when he saw how excited these people were.

"In that case, I'll show you my new baby."

While speaking, he directly took out a book...

Shire University physics textbook.

"Look, knowledge in this physics book is invaluable. When I was studying physics recently, I discovered that the study of sound waves can lead to different insights into music, and a more thorough insight into the nature of music that moves people. Let's study it carefully. , look here..."

(There is no limit to learning, the older you get, the more you find that the amount of knowledge you have is far from enough. You can really read more books when you have free time. Regardless of the type, this is a kind of spiritual enrichment. Of course, the premise is that you can read more books after work every day have time.)
