Reflected Light can be Reflected again

Multiple reflections can be obtained by placing more than one mirrors at certain angles to each other which results in reflection of light for multiple times between the reflecting surfaces. This phenomenon is used in certain scenarios such as:

  1. In a Periscope to see hidden objects
  2. In a kaleidoscope to see beautiful patterns
  3. In a barbershop to see the back of the head of a person getting a haircut
