13.2 Refraction--The Bending of Light As Its Speed Changes

Cause of Refraction

Refraction occurs when a wave bends into a medium into which it travels at a different speed. Duration: 1:29.

Refraction of Light

Snell’s law extends to mirages and other examples of refraction. Duration: 8:46.

Refraction of Light

The refraction of light that occurs when passing through two different mediums is likened to what happens when a set of wheels rolls over two different surfaces. Duration: 2:47.
