[You kid, you left early, didn't you? 】

When Li Mu received the news from Director Wu, he was stunned.

Clams?

How did Director Wu know that he left the scene early?

Then Wu Mengyuan's message came again.

[Do you know how many people behind you left the scene early because you left the field and then left the field with you? More than a dozen people left within 100 minutes of the start of the exam! 】

Seeing this news, Li Mu was stunned again, and finally couldn't help sighing.

Sure enough, someone left the venue early.

And within 100 minutes of the exam, there were so many people.

Sure enough, Director Wu's question was still simple.

This can't close the gap.

Fortunately, he wrote it a little more seriously, and he must have scored a full score, so the problem should not be very big.

Then he replied, "That's good! It shows that under the leadership of Professor Wu, our Department of Physics is full of talents and is thriving, and more than a dozen people can complete all the questions in less than 100 minutes after the exam, which also shows that you are not too embarrassed for me, let us all go! #大拇指#大拇指#抱拳#抱拳】

I can't point out positively that Professor Wu's question is simple.

He still understands this truth.

As a result, Professor Wu did not reply for a long time, until finally sent him a 60-second voice message.

Hey......

Why did Professor Wu send such a long voice?

Sixty seconds seems like the maximum limit, right?

Since he was in the library, he put on his headphones and listened to the voice.

"You kid is sincere in trying to me off, old fellow, right?"

"The dozen or so people other than you basically handed in the blank papers, you are a good leader, I was going to write down the names of you who submitted the papers in advance, but I didn't expect you to be the first to hand in the papers."

"What else is full of talents, do you kid just think my question is simple?"

"Do you want me to open a separate exam room for you in the future? Let your kid take the test on his own? ”

"And ......"

“…… I'll ...... next time."

Sixty seconds, Wu Mengyuan's barabala, and in the end, it stopped abruptly before he finished speaking.

Obviously, 60 seconds is not the limit of Professor Wu, but the limit of WeChat.

After sending this voice, Professor Wu sent a message.

[You come to my office now.] 】

What else can Li Mu say about this?

Naturally, I could only respond quickly: [Okay professor! 】

Touched his face, he misunderstood the feelings?

In addition to him, the more than a dozen candidates who submitted in advance basically handed in blank papers?

Is it that hard......

He thought about it for a moment, and finally he shook his head.

He thought about the reasons why he couldn't figure it out for a long time for others in his mind, and then reviewed the difficulties of those questions, and he found ......

Have it?

Forget it, don't care so much for now, Professor Wu will look for him, and he will have to pass.

It seems that the horse's fart just now was accidentally slapped on the horse's leg, and I will have to smooth Professor Wu's temper later.

So he stopped what he was doing for a while, and then left the library and went to Professor Wu's office.

……

Soon, Li Mu arrived.

When he entered the office, he saw Professor Wu looking at him with an angry expression.

"You kid thinks my question is simple, don't you?"

Straight to the point, Wu Mengyuan expressed the source of his anger.

Just kidding, he came up with difficult questions, which was famous, and now he is underestimated by this young man?

"Ah...... No no! Li Mu shook his hand again and again, "I didn't say it!" ”

"Your hint when I didn't see it?"

Wu Mengyuan waved his hand and said, "You can get a full score, the teacher is very happy, but you say that the question is simple, the teacher is not happy." ”

Immediately, he brought a piece of paper from the side and put it in front of Li Mu, "Come, you can do this question." ”

"Ah......h

Li Mu was stunned, question?

In the end, he reacted, feeling that Professor Wu was planning to find a field with him!

Cough!

Then this question should be a little interesting.

"Okay professor."

So he took the piece of paper and looked at the question.

[Considering a particle moving in a one-dimensional potential well, the particle mass is m, and its potential energy V(x) is expressed as V(x)=...... In either of these quantum states, the particle can be described as a de Broglie wave with a standing wave form, and the boundary of the potential well is the wave node. 】

[1. Determine the minimum energy value that can be taken by quantum particles in the potential well; 2. Write the expression of En; 3. Write the expression λ21 for the wavelength λ21 of the photons emitted by the particle when it transitions from the first excited state (E2) to the ground state (E1). 】

Seeing this question, Li Mu was stunned at first.

This is...... The content of quantum mechanics.

He raised his head and glanced at Wu Mengyuan.

Wu Mengyuan glared back, "Look at what I'm doing, write your question." ”

Li Mu immediately retracted his gaze, and then continued to look at the question in his hand.

He guessed, it seems that Professor Wu really wanted to get back on the field, and actually came out of quantum mechanics, which he only started learning in his junior year.

Of course, among the three questions in their competition, the third question is also the question of quantum mechanics, and in the subsequent international college physics competition, quantum mechanics is also within the scope of the syllabus.

However, for him, he has already finished learning all the quantum mechanics of undergraduate physics, and at the same time, he has already expanded both deeply and widely, and he can still do such quantum mechanics problems.

If you want to come to this question, it must be very difficult.

Thinking of this, he began to analyze the question.

Not......

Well......

Yes?

After spending a minute of analysis, Li Mu didn't know how to express it.

Hiss......

It seems like...... It's not that hard, is it?

It's a little more difficult than the third question in the exam just now, but the degree of difficulty is not very high.

This......

He secretly glanced up at Professor Wu again.

After discovering that Professor Wu was still looking at him, he quickly withdrew his gaze.

It seems that it can only be played in one wave.

As soon as I thought of this, my acting skills were immediately brought into play.

What frowns and ponders, what scratches his ears and scratches his cheeks with a blank face......

At this moment, he seems to be possessed by a drama spirit, and the question is comparable to a world-class problem.

And Professor Wu on the side looked at Li Mu pretending to be there expressionlessly.

Li Mu secretly took a second look at him just now, and then immediately put on a difficult look, and he immediately saw through this kid's acting skills.

Oh, young man.

I've seen more plays than you eat salt.

It's still loaded.

He began to give Li Mu this question, and he was a little embarrassed in his heart, because he knew how difficult this question was, and his mastery of the amount of knowledge was relatively high, and Li Mu was only a freshman, if the amount of knowledge did not reach that level, it would definitely not be enough.

But now......

He wasn't embarrassed at all.

It seems that my questions are still simple.

Merely......

Is there really a test question under this kind of test-oriented education, can it be difficult for this kid?

He couldn't help but have such a question in his heart.
