When light wave is passed from one medium to another, one part of the light is reflected back to the earlier medium, one part is transmitted to the second medium and one part is absorbed in the border.
The transmitted part is slightly bent. This phenomenon is called Refraction.

It depends whether the new medium is "heavier" or "lighter" than the previous medium. If it is "heavier" then the wave slows down. If it is "lighter" the wave speeds up.

An electromagnetic wave does not need a medium. It is able to pass through a vacumn.
It refracts some and reflects some.

A mechanical wave travels through a medium because a medium is necessary for the propagation of that wave. With a mechanical wave, like sound, mechanical energy is put intothe wave, and the medium carries the energy of the wave. This is in contrast to an electromagnetic wave (like light) which can move through a total vacuum.
As light rays pass from one medium into another, they bend (or "refract"). This can be easily seen by trying to poke at something under water from above the surface (for example, aim a drinking straw at a target in a glass of water). This refraction is a consequence of the change in direction due to the wave-qualities of light, as the speed of the light is affected by the change of medium.
The bending of a wave as it moves from one medium into another is called refraction.

The particles of the medium will gain some energy. The exact effect will depend on the nature of the wave as well as that of the medium.
A wave can only pass through a medium
