Law Of Refelction
Reflection is the bouncing back of a ray of light, sound, to heat when the ray hits a surface that it does not go through. Light reflects on off surfaces the same way that a ball bounces off the ground, so the Law of Reflection states that the angle of the incidence is equal to the angle of the reflection.
Types of Reflection
A mirror's surface is very smooth so the reflection will reflect at the same angle in the opposite direction.
