Question

prove that incident angle is equal to angle of reflection

Answer 1

Before understing this plzz note this is based one the principal of fermate who says that light takes always quickest path not shortest
so ,

to prove this do the following process-

◆Suppose there is plane surface near are a two poles at the end ,

◆between the pole there is a snake and in one either pole there is a crow

◆ crow will take quickest path to capture its pray

◆First crow will come from either pole after Catching it will go on other pole which makes a ray like angle of incidence and angle of reflection

◆it is proved because everyone whether crow other thing always take quickest path to travel like light

◆ therefore , Angle of incidence = Angle of reflection

hope this helps u
