Question

How is it that light is reflected in this way in these photos?

Answer 1

The light will reflect off the mirror in a more orderly way than it reflects off your clothes. We call that specular reflection—it's the opposite to diffuse reflection. How does the mirror reflect light? The silver atoms behind the glass absorb the photons of incoming light energy and become excited.

Answer 2

Light always follows the law of reflection, whether the reflection occurs off a curved surface or off a flat surface. The task of determining the direction in which an incident light ray would reflect involves determining the normal to the surface at the point of incidence.
