Refraction - Wikipedia
In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. [1]

25.3: The Law of Refraction - Physics LibreTexts
The changing of a light ray’s direction (loosely called bending) when it passes through variations in matter is called refraction. Refraction is responsible for a tremendous range of optical phenomena, …
Physics Tutorial: The Cause of Refraction
As light passes across the boundary from one material to another, it undergoes a change in speed. This change in speed is accompanied by a change in direction of the path of light. We call this change in …
Refraction - Math is Fun
Refraction is the "bending" of light (or any electromagnetic wave) when entering a different medium. When electromagnetic waves enter a different medium the speed changes. The frequency stays the …
