A ray of light strikes a plane mirror such that its angle of incidence is 300 . What angle does the reflected ray make with the mirror surface?

Dear Student

I am hoping that angle of incidence is 30^o not 300. So i am solving questions considering same.

As per law of reflection
Angle of incidence is equal to angle of reflection  that
Angle i = Angle r
So, Angle of reflection r = 30^o
So reflected ray makes angle  (90^o - 30^o) to mirror surface that is 60^o.
