Refraction of light which is bending of light,occurs when the light passes through a medium that is of different density.
When the light pass through a denser medium from a less medium,the light ray will bend towards the normal.
When the light moving from a denser medium to a less dense medium,it will bend towards the medium.
Look at the following Example:
Refraction of Light
