Answer: The correct answer is " bounces off an object".
Explanation:
Reflection occurs when a wave bounces off an object.
For example, when a ray of light incidents on the surface of a plane mirror. The light gets reflected from the plane mirror because of the silver polishing on the backside of the mirror.
There are two laws of reflection:
(1) The reflected ray, the incident ray and the normal to the surface of the mirror are all lie in the same plane.
(2) The angle of reflection is equal to the angle of incidence.
