Question

As light moves from air to water ,the path of the light can bend and change direction as it continues through the water.what is the name of this phenomenon

Answer 1

The phenomenon you are describing is called **refraction**. Refraction occurs when light travels from one medium to another (such as from air to water), causing a change in its speed and a bending of its path. This bending of light is governed by Snell's Law, which relates the angle of incidence and the angle of refraction to the indices of refraction of the two media.
