When light bounces back at the same angle it hit an object, this is called reflection.

Here's a breakdown:

* Reflection: The process where light waves bounce off a surface.

* Angle of Incidence: The angle at which the light ray strikes the surface.

* Angle of Reflection: The angle at which the light ray bounces off the surface.

* Law of Reflection: The angle of incidence is always equal to the angle of reflection.

Think of a mirror. When you shine a light beam at a mirror, the light bounces back at the same angle. This is a classic example of reflection.
