Physics for IGCSE & O level - Rays And Waves (Section 8 - No. 14)
What happens to the angle of refraction when the incident light travels from a medium with a lower refractive index to a medium with a higher refractive index?
The angle of refraction is greater than the angle of incidence.
The angle of refraction is equal to the angle of incidence.
The angle of refraction is less than the angle of incidence.
The angle of refraction remains the same.

When light moves from a lower refractive index to a higher refractive index, the angle of refraction decreases (bends towards the normal).
