Here we see an example of ideal specular reflection, where the surface causes an incident light ray to reflect into a single outgoing direction. For many other materials, light can get absorbed or transmitted through a surface as well, but for a mirror, it reflects nicely so we can see things "on top" of the mirror. In these cases, the law of reflection applies.
