प्रश्न
Show an incident ray AO and the normal ON a plan mirror. draw the reflected ray and then find the angle between the incident and reflected rays.

उत्तर
Since the angle of incidence = 60°.
From the diagram, the Angle of reflection to the normal = angle of incidence to the normal = 60°.
So, the angle between the incident ray and reflected ray = Angle of incidence + Angle of reflection = 60° + 60° = 120°.
