我是在香港读书的学生,我的物理课本有提过相关的知识,我就翻译给你啦,希望能帮到您吧
原文:
Critical angle is the angle of incidence at which the angle of reflection is 90°. If a light ray hits the surface at an angle greater that this, it is totally reflected inside the block. In this case, the surface acts like an plane mirror. This phenomenon is called total internal reflection.
中翻:
当折射角等于90°, 那只入射角就叫做临界角。当光线射入的角度比这大的时候,它就会在物件内被完全的反射。在这个情况下,它的表面就像一面镜子。这个现象被称为全内反射。本回答被提问者和网友采纳
