पर्याय

• equal to the angle of incidence

• greater than the angle of incidence

• smaller than the angle of incidence

• 45°

Answer 1

A ray of light travels from glass into air. The angle of refraction will be greater than the angle of incidence.

Explanation:

Light speeds up travelling from dense glass to rare air, bending away from the normal (r > i).
