What statement below best describes the refraction of light?
A) The absorption of light as it travels though a dense, transparent material.
B) The spreading out of white light according to wavelength.
C) The change in direction of a light ray as it passes to a medium of different optical density.
D) The change in direction of a ray of light as it reflects off a surface.

Question

Quizplus · Accepted Answer

Refraction is the change in direction of a light ray as it passes to a medium of different optical density. This is what causes the bending of light when it travels from air to water or from one material to another with a different refractive index. Refraction is the change in direction of a light ray as it passes to a medium of different optical density. This is commonly observed when light travels from air to water or from air to glass, causing a change in the direction of the light ray.
