Question

How do mirrors function?​

Answer 1

Answer:

Light passes through the glass part of the mirror and is reflected by the metal. The layer of paint at the back of the mirror serves a similar protective function, keeping the metal in place. ... When rays of light hit rough surfaces, they bounce the light back in all directions.

Answer 2

Answer:

The key factor is a smooth surface, because rough surfaces scatter light instead of reflecting it. When photons — rays of light — coming from an object (your smiling face, for example) strike the smooth surface of a mirror, they bounce back at the same angle. Your eyes see these reflected photons as a mirror image
