When light enters from denser medium to rare medium in what direction does it turns?

It depends what angle it incidents on. For example: if the light was at right angles it wouldn't turn at all.
It is best to think of the mediums as two different road surfaces and the light as a car. As the light (car) comes from a dense medium (dirt) onto a rare medium (tar) it will go faster on the side that first touches the rare medium, and hence, turn it.

When light enters from denser medium to rare medium what happens to its phase change?
phase angle of 0 degree
Why light bends towards normal when it enters from optically rare to optically denser medium why it does not bend away from the normal?
This is because of the speed of light getting reduced as it enters into the denser medium. Think of the FRONT of the wave as it enters a more-dense medium at an angle, and its speed decreases. Vizualize it in very slow motion: -- The wave-front arrives at angle, so part of it is across the boundary and into the new medium, while part of it is still out in the old medium. -- The part of the wave-front in the new medium is traveling slower, while the part that hasn't quite reached the boundary yet is still out in the old medium and traveling faster. -- If your vizualization is running accurately, this action is causing the whole wave-front to turn, becoming more parallel with the boundary, and its direction of motion turning toward the normal.
What is the speed of light in oil?
Einstein says that the speed of light is the same to all observers. This raises some interesting problems and his theories of relativity set out to solve them. But that aside, the speed of light is the same in olive oil and a diamond as it is anywhere else.
When light waves enter a new medium and bend what occurs?
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.
What happens to the intensity of light when it enters a dnser medium?
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
Why is white light dispersed when it pases from one medium to anonther?
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 from denser medium to rare medium what happens to its phase change?
phase angle of 0 degree
Is it necessary to have a denser medium for the reflection of light?
no. if the medium is denser, the reflection of light would not do it.

What is refracted light?
The refraction of light is the change in direction of a light ray when it crosses a boundary between two transparent substances. Refraction of light is the change in direction of a light ray due to a change in its speed as it goes from one medium to another.The speed and wavelength of a light ray change when this occurs, but the frequency remains the same.When light travels from denser medium to rarer medium it moves away from the normal [line at right angles to the boundary] and when light travels from rarer to denser it moves towards the normal.
What is effect on wavelength of light when it enter dense medium?
When light enters a denser medium than it was previously travelling in, the wavelength gets shorter because the speed of the light slows down: v=w/f where v is the velocity of a wave, w is the wave length, and f is the frequency. When light enters the new medium, f does not change but v decreases so w also decreases. Actually, the density of the medium is not accurate. The medium is not denser it just is "optically denser" which means it has a higher index of refraction. It has nothing to do with actual density, which is weight divided by volume.

A ray of light travelling from medium A to medium B bends away from the Norman Which medium is optically denser?
Medium A is the more optically dense medium. As when the light enters B its speed increases taking it toward the normal.
Why light bends towards normal when it enters from optically rare to optically denser medium why it does not bend away from the normal?
This is because of the speed of light getting reduced as it enters into the denser medium. Think of the FRONT of the wave as it enters a more-dense medium at an angle, and its speed decreases. Vizualize it in very slow motion: -- The wave-front arrives at angle, so part of it is across the boundary and into the new medium, while part of it is still out in the old medium. -- The part of the wave-front in the new medium is traveling slower, while the part that hasn't quite reached the boundary yet is still out in the old medium and traveling faster. -- If your vizualization is running accurately, this action is causing the whole wave-front to turn, becoming more parallel with the boundary, and its direction of motion turning toward the normal.
