Xueba's Sea of ​​Stars

Chapter 106 Ranking announced
After checking his identity, Wu Bin soon went to the examination laboratory under the guidance of the teacher.

"As expected of a university laboratory..." Looking at the huge and bright physics laboratory, Wu Bin couldn't help feeling in his heart.

Then the invigilator announced the rules of the test room and various precautions. At 10:[-], the test started on time.

There is only one experimental question, which is required to study the physical properties of optical glass materials (wavelength range is 400~700nm)

After reading all the experimental devices, materials and three questions, Wu Bin couldn't help breaking out in a cold sweat.

"Wow, it's really coquettish..."

There are two main tools used in this experiment. One is the common spectrometer, which is used to measure the angle, and then obtain some physical parameters, such as grating constant and refractive index.

The other monochromator is not often used, but the basic physical principles are also mentioned in the competition textbooks, so Wu Bin is no stranger.

But this experiment is a combination of these two experimental instruments!

This is fresh!At least Wu Bin has never played it...

"As expected of the final experiment question, it's really cool..."

It's all about Sao, but it's not so disgusting that Wu Bin can't do anything, it just needs to use more brains.

So Wu Bin adjusted the spectrometer first, then inserted the sleeve at the exit slit of the grating monochromator into the collimator tube of the spectrometer, turned on the power and turned on the LED...

As he was doing it, Wu Bin suddenly discovered that the questioner was quite conscientious, and actually reminded many details in the test questions.

For example, don’t ask whether the physical performance of the self-made small grating monochromator is very stable, whether the spectrometer has readjusted the relevant components before performing a large-scale readjustment, etc.

The difficulty of the first question is not too high, as long as you can use the experimental equipment proficiently, you can complete it.

However, the second question is that the experimental principle of measuring the dispersion curve of glass materials is quite cumbersome.

"Tsk..." Wu Bin closed his eyes and meditated for a while.

'The dispersion phenomenon of optical materials refers to the macroscopic performance of the material's refractive index n or absorption coefficient α changing with the light wavelength λ...'

'Um!Got an idea! '

Wu Bin couldn't help snapping his fingers, and then began to use the spectrometer to measure the minimum deflection angle of the monochromatic light wave corresponding to the [-]-way mirror.

As long as you have an idea, the experimental questions are relatively easy to follow. Although the process was a bit difficult, Wu Bin finally completed the final third question after spending two hours.

……

When he returned to the hotel after the exam, Wu Bin saw what he expected. There were gloomy candidates "wandering" everywhere in the hall.

Because he still thinks he is very strong in the experimental questions, and this question that even he thinks is embarrassing, even the group of heaven's favorites who can enter the national competition, probably will be disgusted.

The assembly point agreed by the Shanghai team was on the second floor. When Wu Bin walked up, he found that almost all the others were already there, and they were hugging each other and cursing their mothers.

"It is said that the experimental questions are for warmth???"

"Let's not talk about it, this question is really good, and my scalp is numb. It took me an hour and a half just to find the crosshairs reflected from the flat mirror back into the telescope! There is no time to do it later."

"I also adjusted the axis of the optical axis to be perpendicular to the rotating axis of the instrument for a long time. Wow...it's really great."

……

Such complaints are generally heard quite rarely, because the unwritten rule is that the content of the test is not discussed after the test.

But it is estimated that the experimental questions this time are too outrageous, which is why everyone complained wildly.

"Hey, God Wu is here, aren't the experiment questions exciting?" Lu Xuange shouted as soon as he saw Wu Bin.

"Exciting, indeed exciting." Wu Bin nodded.

"Yeah~ let me tell you..."

So until dinner time, almost everyone was complaining about this experiment question. Although Wu Bin felt that some of the details they complained about were actually reminded in the question, but they didn't pay attention, but it's better not to talk about it at this time.

After all, many times you can see through but not tell, but you are still good friends.

But no matter how torturous the process is, how unacceptable the result is, this time the National High School Physics Competition has finally come to an end, and the rest is to wait for the announcement of the scores and rankings.

Wu Bin didn't have dinner with everyone. His two teachers came all the way, so he naturally wanted to accompany them.

It was quite interesting to chat with the two teachers about the theory test and experimental questions during the meal.

……

Before the announcement was made the next morning, the competition committee organized the students to visit the Hongyan Link, including Hongyan Village, Baigongguan, and Zhazidong, which enhanced the party spirit of a wave of students.

However, the teacher could clearly feel that the students had no interest in sightseeing, so they returned to the hotel early after visiting.

After eating a buffet, at 4 pm, the score... finally announced.

"Mom, I'm a bit afraid to check."

The Shanghai team got together early, and now Zhao Kehan ​​standing next to Wu Bin was covered in sweat.

"There's nothing to be afraid of. Stretching out your head is a stab, and shrinking your head is also a stab. Why don't you hurry up." After Lu Xuange finished speaking, he went to check the points.

"Fuck!!!"

Just when everyone was struggling, Lu Xuange suddenly uttered a foul language.

"What's the matter, you entered the national team? So excited." Xiao Songyang glanced at Lu Xuange and asked.

"I haven't seen whether I can make it to the national team...but Wu Shen is in, he's the number one! Fuck, I don't know what to say other than f*ck!"

Lu Xuange's words made everyone startled, and even Wei Tianshuo stood up in fright, and quickly looked at the newly announced ranking list with his classmates.

Province: Shanghai, School Name: Xiaguang Middle School, Student Name: Wu Bin, Gender: Male, Grade: Senior Three, Theory: 270, Experiment: 79 Total Score: 349 Rank: 1
Province: Hubei, School Name: No.265 High School Affiliated to China Normal University, Student Name: Gong Chengwei, Gender: Male, Grade: Senior Two, Theory: 75, Experiment: 340 Total Score: 2 Rank: [-]
Province: Hunan, School Name: Yali Middle School, Student Name: Zhang Fu, Gender: Male, Grade: Senior Three, Theory: 255, Experiment: 70 Total Score: 325 Rank: 3
……

"My god... God Wu is awesome!" Zhao Kehan ​​slapped Wu Bin hard and shouted after watching.

"You're so strong! You're as good as the monster in second place, beating No. 3 by more than [-] points! What the hell... my knees are a little weak."

"To be honest, I really didn't expect this. Although I knew God Wu was powerful, I really didn't expect... God God! God Wu! Let me hug your leg!"

……

After checking the score, the rest area on the second floor was in total chaos, and Wu Bin, the person involved, was actually in a very delicate mood at the moment.

'My theory question was deducted 10 points? ? ? '

You must know that he is confident that he can get full marks after finishing the work, and now he is really uncomfortable!
