Question 12

The following diagram shows an incident ray AO and the normal ON on a plane mirror. Find the angle of incidence and angle of reflection.

The following diagram shows an incident ray AO and the normal ON on a plane mirror. Find the angle of incidence and angle of reflection. Light Energy, Concise Physics Solutions ICSE Class 7.
Answer

Normal ON is perpendicular on plane mirror, so

Angle of incidence = 90° - 30° = 60°.

Angle of reflection = 60°. (Since angle of incidence = angle of reflection)
