在高中物理的光学教学中,双缝干涉实验一直是教学的重点与理解的难点。托马斯·杨在他的《自然哲学讲义》中是这样描述该著名实验的:把一支蜡烛放在一开了一个小孔的纸前面,就形成了一个点光源,在纸后面再放一张纸,并在第二张纸上开两道平行的狭缝,从小孔中射出的光穿过两道狭缝投到屏幕上,就会形成一系列明暗交替的条纹。这个实验在历史上首次证实了光的波动性。在实验中的小孔或单缝的目的是什么?双缝的
In high school physics optical teaching, double-slit interference experiment has been the focus of teaching and understanding of the difficulties. In his Handbook of Philosophy of Nature, Thomas Young described the famous experiment as follows: Putting a candle in front of a small hole of paper creates a point light, placing a piece of paper behind the paper Paper, and in the second sheet of paper to open two parallel slit, the light emitted from the hole through the two slit into the screen, it will form a series of alternating light and dark stripes. This experiment for the first time in history confirmed the volatility of light. What is the purpose of the hole or single slit in the experiment?
