This is called refraction due to differences in the speed of light in the different mediums.
Refraction.
Refraction is the bending of light waves as they pass from one medium to another.
When a ray of light travels from one transparent medium into another medium, it bends while crossing the interface, separating the two media. This phenomenon is called refraction.

The difference in refractive index of different media affects the bending of light! The density of the medium also plays a key role in it! As the density changes the speed of the light also changes! The extent up to which light bends (refracts) is purely based on the refractive index of that particular medium (sin i/sin r)! If the angle of incidence of the light is is greater than the threshold value ie., the critical angle light gets totally reflected into the medium else light gets refracted! Critical angle varies for each medium!
when light travels from one medium to another it deviates from its normal path. the deviation is dependent on the refractive index of the medium. Bending of light ray also depends on the thickness of the medium. therefore more the thickness more is the deviation caused and more is the bending.
Refraction.
In a single homogeneous medium (electrical properties constant throughout the medium), the speed of light is constant ... although less than its speed in vacuum ... and the light does not bend. Bending (refraction) only occurs at the boundary between different media in which the speeds are different, or in a single medium whose properties change gradually (like the atmosphere).

The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
Yes, it travels in waves, but it doesn't need a medium.
If the light travels faster in the second medium, then this medium is called the rarer medium.
