A special case of the relativistic Doppler effect, which occurs when light reflects from a moving mirror, is discussed. The classic formula for the Doppler shift is derived in a fully non-relativistic fashion using basic facts from geometry. The derivation does not involve Lorentz transformations,...

解析 B。本题涉及光学知识。A 选项“absorbs light”指吸收光,镜子不吸收光;B 选项“reflects light”意思是反射光,镜子通过反射光让我们看到自己的影像,符合题意;C 选项“transmits light”表示透射光,镜子不透射光;D 选项“blocks light”说阻挡光,镜子不是阻挡光而是反射光。
The reflection of light describes how light bounces off surfaces. When a light ray hits a surface, it changes direction or is reflected. What is the Reflection of Light? Whenever a person looks in a mirror or sees the moon, they are seeing the reflection of light. But what is t...
