It changes direction, according to Snell's Law.
It bends.
It is redirected as it passes through a medium.

When a ray of light passes from a rarer medium to a rarer medium, it will continue in a straight line and its speed will remain constant. There will be no change in the direction of the light ray.
Light can be both reflected and refracted when it passes through a transparent medium. Reflection occurs when light bounces off the surface of the medium, while refraction happens when light changes direction as it moves through the medium.
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 occurs when light changes direction as it passes from one medium to another, such as from air to water. This bending of light is due to the change in speed of light as it enters a denser or less dense medium, causing the light rays to change direction.
When light passes from one medium to another with a different refractive index, andnot in a direction perpendicular to the boundary between the media, its speed changes.
When light passes from a liquid to a solid medium, its speed typically decreases, as solids usually have a higher refractive index than liquids. The wavelength of the light wave will also decrease as it enters the denser medium, causing the light to bend towards the normal.
No,its called refraction. this actually happens when the light passes from one medium to another and thus the velocity of light changes, which enable the light to bend.
The answer depends on what on earth you mean by the "dirtier" of a wave.
