When you have two different medias but with the same refractive index, light does not refract (bend).
Yes, Light bends towards the normal when it travels from air to another medium and bends away when going into air from another medium. This can be affected by the angle of incidence and what angle it is.
Light moves at the speed a medium permits. It is "handed off" to each bit of material in turn. One "side" of light encounters the different medium before the other, and so a turn is involved. Think of drivng a car along a road, with one tire on smooth pavement, and the other tire on rough pavement. You have to slightly turn the steering wheel to keep from turning across this interface between smooth (low n, high speed) and rough (high n, lower speed). Light *has* no steering wheel.
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
When light traveling at an angle passes from one material into another, it undergoes refraction. Refraction is the bending of light as it passes from one medium to another, due to the change in the speed of light. The degree to which the light bends depends on the angle of incidence and the refractive indices of the materials involved.
The ray of light bends towards the normal.
Refraction
the light bends
It is called "refraction".
Light bends because of the difference of speed in each medium.
Yes, Light bends towards the normal when it travels from air to another medium and bends away when going into air from another medium. This can be affected by the angle of incidence and what angle it is.
Refraction, which is the bending of light
When light is Refracted it bends when it travels from one medium to another
Index of Refraction
The bending of a wave as it moves from one medium into another is called refraction.

Everybody knows change in speed of light causes to bend light. But why does light bends towards normal when passing from rarer to denser and vice versa?
Refraction is the change in direction of a wave when it reaches a boundary between two media due to traveling at different speeds in each medium.
