大自然有许多神奇之处 ,肥皂膜的彩色条纹就是其中一例 .我们知道白光照射到肥皂膜上后 ,会看到膜上有许多彩色的条纹 .你知道它们是如何形成的吗 ?当光照射到肥皂膜上后 ,从膜的前后两表面分别反射的光在前表面处相遇 ,由于它们来自同一列波 ,频率相同 ,满足干涉条件 ,于是就? Nature has many wonders. The color stripes of soap film are just one example. We know that after white light hits the soap film, we will see many colored stripes on the film. Do you know how they are formed? When the light is shining On the soap film, the light reflected from the front and back surfaces of the film respectively meet at the front surface. Since they come from the same column, the frequency is the same and the interference condition is satisfied.
