From the school physics I know that the material objects bounce from the plainplane surface at the same angle, losing some kinetic energy. In the same school I was taught that the light (and waves in general) obeys this principalprinciple too.

Obviously, in the case of light the plainplane surface should be a perfect mirror. But I can't understand how should this work from the quantum point of view. Let's assume that our mirror consists of a single silver atom.

Why should the electrons of this atom re-emit consumed photons at some specific angle?

No need to name silver in Latin.

Obviously, in the case of light the plain surface should be a perfect mirror. But I can't understand how should this work from the quantum point of view. Let's assume that our mirror consists of a single Ag (Argentum, silver) atom.

Why is the light reflected at the same angle from mirror?
