refraction
The direction of light propagation can be changed at the boundary of two media having different densities. This property is called refraction, and is illustrated in the following figure for the boundary between air and water.

Water and air are different when it comes to light passing through them. This is called refraction.
It is known as refraction.

Light is normally not thought of as "bouncing" but being reflected."Bending" is called refracting when it comes to light and is caused by the light going through materials with different optical densities (air, water, and glass, though all clear, have different optical densities - indexes of refraction).Reflection can occur when two materials with sufficient differences of index of refraction are at a surface and the light hits them at an angle that is greater than a certain value - total internal reflection. Reflection can also occur when light hits a surface that is sufficiently flat and that surface is made up of a material with many free electrons (such as most metals) - a mirror.
