Question

Quizplus · Accepted Answer

When light travels from a less-dense medium (like air) to a more-dense medium (like water or glass), it slows down and the angle of incidence is decreased. This causes the light to bend toward the normal, which is an imaginary line perpendicular to the surface at the point where the light enters the medium.
