Reflection occurs when light bounces off a shiny or smooth surface. How much reflection depends upon how even the surface is. If the surface is rough, the light scatters. If the surface is smooth and flat, the light will bounce off it at an equal and opposite angle. This is why a flat mirror reflects a good likeness of the object being reflected.
Light changes direction when it reflects. The angle the light comes in is the same as the angle it goes out.
Highlight in the section below to find out the answers to the anchor phenomenon questions.
Mirrors (and other reflective surfaces) reflect light that reaches them. The angle at which light strikes the mirror (incidence angle) always matches the angle at which reflected light leaves the mirror (reflected angle). In a flat mirror, that looks like this:
Curved mirrors take advantage of that relationship, and different parts of the mirror reflect light in different directions, altering what we see this:
