Light rays travel in different mediums at different speeds. In vacuum, for example, light travels at the speed of 3×10*8m/s. This is the highest speed possible in physics.

One of the most important parameters that measures optical properties of a medium is the index of refraction. It is defined as the ratio of the speed of light in vacuum (3×10*8m/s) and the speed of light v in the medium in question. 
The refractive index measure the optical density of a given material. A material with higher refractive is more optically dense than a material with lower refractive index.

Answer:- Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction.
