物理听力是这样的：
听力原文：
男：My good colleague, isn't this right? When I saw that the current loop was clearly open, why did the sensitive ammeter deflect?
女：Because our cathode material emits hot electrons. When electromagnetic waves bombard the cathode material, electrons are ionized.
男：So why don't the light bulbs in our laboratory cause this effect?
女：Because the electromagnetic waves emitted by the light bulbs in the laboratory are too long and too low in frequency to ionize electrons. To produce this phenomenon, you need to use ultraviolet radiation.
男：I see, that is to say, electron dissociation requires an energy, and the higher the frequency, the greater the product multiplied by Planck's constant, making ionization more likely to occur
女：That's right
问题：他们两个到底在做什么实验?
A多普勒效应实验
B迈斯纳效应实验
C光电效应实验
D霍尔效应实验

第一题显然是tomorin效应，多普勒效应只与速度有关

现在物理这么难吗[doge]我高考的时候没有什么多普勒效应，大题就一个运动，一个电磁学
