The bending of a wave as it passes through one medium to another medium is called as refraction.
How to explain refraction?
In the phenomenon of refraction, there is a change in the speed of propagation of light by means of a deviation from the original direction, that is, the light undergoes an angular deviation in relation to the normal line, so that it passes from a transparent medium to a different transparent one.
In this case is refraction because changes in the speed of light due to a change in the propagation medium.
