Question

A incident ray makes an angle of 30 degree with a plane mirror,what will be the angle of reflection

Answer 1

Incident ray makes 30° with plane mirror

But taking normal,
angle of incidence = 90 - 30 = 60°

angle of incidence = angle of refraction

So, angle of reflection = 60°

Hope This Helps You!

Answer 2

Answer:

60°

Explanation:

angle of incidence = 90° - 60° = 30°

therefore , angle of incidence = angle of reflection = 30°
