diffraction
Waves are said to have been refracted when they bend upon changing mediums. The waves have undergone refraction when moving from one medium to another.
Waves may bend if they move from one medium to another.
Light bends because of the difference of speed in each medium.
change of medium causes light to bend

It must pass though a medium from an another medium.

As you should know, as light travels from one medium into another more optically dense medium (such as from air into water) the light is refracted towards the normal. But why does the light appear to bend and refract? Light acts not only as a particle, but also as a wave. When the light hits the more optically dense medium it slows down. This also happens with water waves. As the waves come towards the shore the ocean becomes more shallow and they speed up, when the water waves speed up they bend away from the normal. The same thing is happening with the light waves. As light waves are hitting the more optically dense material, because they slow down they oppose and opposite effect to the water waves and bend towards the normal. I hope this helped. :)
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of refraction.

The bending of a wave occurs when the wave hits a object?
The object refracts the light, because of the bending of light or waves as it passes from the material to another.
The particles compress and refract, passing along the energy. It travels faster in mediums with particles that are more tightly packed eg. moves faster in metal as opposed to wood. Also, the more dense the air, the faster sound waves travel.
As light passes through a prism, it is bent by the angles and plane faces of the prism. This is called refraction and is defined as the fact of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.
