But the good news is that there are very few optoelectronic questions in this monthly physics exam, and they are all relatively simple.
When I left the examination room, the sun was shining brightly, and my body and mind were relaxed.
Just as I was about to leave the school, I ran into Sang Wan by chance.
Jiang Wuyang's legs had almost recovered by now, and he could walk normally without any problems.
Sang Wan and Gu Peizhi were walking together, and they had just finished their exams.
"Yangyang! What did you choose for the last multiple-choice question in physics?"
Sang Wan was very happy to see Jiang Wuyang.
Hearing Sang Wan's words, Jiang Wuyang subconsciously stopped and said, "Choose B."
When Sang Wan heard this, her face immediately drooped. "Huh? Why? I didn't figure it out, so I randomly picked D."
"The last question is the one about calculating the optical path difference?"
"That problem must be solved using the reflection method. Direct measurement is not an option."
Seeing Sang Wan's depressed expression, Jiang Wuyang kindly explained to her.
Sang Wan frowned and thought hard, wondering if she had figured it out in her head. Suddenly, her eyes lit up: "It seems so! Yangyang, you are so smart!"
Jiang Wuyang smiled softly, his eyes falling on Gu Peizhi beside him: "Senior Gu, can you give me Senior Gu Qingheng's WeChat when you go back? I have a question I want to ask him."
Gu Peizhi stood in the sunshine, the warm light shining on him made him look very gentle.
Gu Peizhi first said yes, then asked curiously, "Can I ask which question it is?"
In his impression, Jiang Wuyang would not ask others for help unless it was a problem that he could not solve at all.
Jiang Wuyang thought for a moment: "It seems that an interferometer measures the intensity of interference light. The laser passes through vertical transmission and reflection. The content is roughly like this. Then the question is to find the circuit."
Gu Peizhi understood it as soon as he heard it. He was not very good at this kind of questions when he first encountered them. It seemed that they had fallen into a trap.
Gu Peizhi found it a little funny and told Jiang Wuyang all the possible misunderstandings he knew about.
Here, Jiang Wuyang and Gu Peizhi were chatting animatedly. On the side, Jiang Yiran, who was passing by, had a pale face and his heart was pounding.
Especially after Jiang Wuyang spoke word by word, he felt dizzy.
