A wave that enters a new medium will experience interference. It is the interference that causes the observed phenomenon we observe when a wave enters a new medium.
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
A light wave can slow down or speed up when it enters another medium. Since the speed of wave motion in general depends on characteristics of the environment, you can always expect the speed of a wave to change as it moves from one medium to another. In the case of sound, it's the mechanical characteristics that matter, whereas for light and other electromagnetic waves, the determining characteristics are the electrical ones. So the speed of light changes when it enters a different medium. Now, since the product of (frequency) x (wavelength) is the wave speed, and the frequency can't change, we notice that if the speed changes, then the wavelength also changes in a new medium. Furthermore, right at the interface ... the boundary between the two media ... if the light doesn't hit the boundary exactly perpendicular to it, then we say that the light is "refracted" at the boundary, meaning that the light leaves the boundary in the new medium in a different direction compared to its direction in the previous medium.
The speed of a mechanical wave depends on the mechanical properties of the medium. When the mechanical properties of the medium change, the speed of the mechanical wave changes as a result. The speed of an electromagnetic wave depends on the electrical properties of the medium. When the electrical properties of the medium change, the speed of the electromagnetic wave changes as a result.
a light ray is refracted when it passes from one medium to another at an angle and its speed changes. at the interface , it is bent in one direction if the material enters in denser and in the other direction if less dense.
When light enters a different medium (refracts), its speed changes.
It changes, in accordance with the optical density of the medium.
When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.

No. The speed of light is determined by the electrical characteristics of the medium it's in, regardless of what medium it came from or what medium it's headed for when it leaves this one.

It reflects a rainbow pattern
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.

Nothing. The speed changes. We live in a universe where electromagnetic waves change frequency if they can't change speed (and in a vacuum they can't), and only change speed if they enter another medium like glass.
The speed of sound depends upon elasticity and inertia of the medium which in turn depend upon the temperature of the medium.That's why speed of sound depends upon the temperature of the medium.
