Question

The second law of reflection states that:

विकल्प

• The angle of reflection = angle of refraction

• The angle of reflection = 2 × angle of incidence

• The angle of reflection = angle of incidence

• The angle of reflection = 90° − angle of incidence

Answer 1

The second law of reflection gives \[\theta_r = \theta_i\]: the angle of reflection equals the angle of incidence, with both angles measured from the normal at the point of incidence.
