A ray of light st

Class 10th Lakhmir Singh & Manjit Kaur - Physics 4. Reflection of light

Answer :

Angle made by the incident ray with respect to mirror surface = 40°

Therefore, angle of incidence= 90° - 40° = 50°

Second law of reflection says that angle of incidence is equal to the angle of reflection.

Therefore, angle of reflection= angle of incidence = 50°
