Refraction
Videos
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. Refraction of lig
A pen partially submerged in a bowl of water appears bent due to refraction at the water surface.
Rainbows are formed by dispersion of light, in which the refraction angle depends on the light's frequency.
An image of the Golden Gate Bridge is refracted and bent by many differing three-dimensional drops of water.
The sun appears slightly flattened when close to the horizon due to refraction in the atmosphere.
