What happens when light hits an object?
The light is reflected off the object.

We see things because of reflected light.
We see red, because red light is reflected blue
because blue is reflected white because all
light is reflected.
6
We see ourselves in a mirror because of
reflection.

The light that hits an object is called the angle
of incidence.
The light that bounces off the object is called
the angle of reflection.
