Refraction
The bending of a light wave as it passes at an angle from one medium to another
Diffraction. Bending of light/sound as it moves from one medium to another - Refraction.
Because of bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density.

The light bends when it passes from one medium to another. But only if it approaches the interface at an angle. In such a case it will still travel slower, but there will be no apparent bending.
Refraction is the bending of light when it passes from one medium to another medium (like from air to glass). The basis for refraction is the speed of light is slightly different in the two mediums. Diffraction is the bending of light that occurs around a sharp edge (like light passing thru a slit). The basis for diffraction is the spreading out of the wave as it passes by the sharp edge.
The light bends when it passes from one medium to another. But only if it approaches the interface at an angle. In such a case it will still travel slower, but there will be no apparent bending.
When a toy car travels from a plain floor to the grass lawn we see that it deflects.Similarly light too bends when it changes its medium.This bending can be seen at the boundary of the two mediums that separates them.
