Refraction of light is a phenomenon in which light rays passing from one medium to another change its direction. Refraction takes place at the interface of two medium of different optical density.
For a light of given wavelength and for a given pair of media, the ratio of sine of the angle of incidence to the sine of the angle of refraction is always a constant. And this constant is called the refractive index of the second medium with respect to the first medium.
Yes and no. Refraction is bending of the light beam and is CAUSED by the fact that light has to travel at different speeds in different mediums. When the light ray slows down or speeds up it bends at the interface of the two media of it is not striking the surface of that medium at right angles.
Light refracts from one medium to another because of differences of speed in each medium; sin(V1)/v1 = sin(V2)/v2.
Refracts
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
Light refracts when it travels from 1 medium to another.if it travels from denser to rarer medium,it bends away from the normal ,which is the perpendicular drawn at a point on the interface of both the surfaces where the light is incident.else it travels towards the normal.air can be considered to be a rarer medium as compared to water.
Refraction is what light does when it travels from one material to another. Refraction is when the light changes direction because it is passing through one medium to another.
It means that when it changes from one medium (substance) to another, there is a change of direction.

Light doesn't have a refractive index. The medium or substance through which the light travels has the refractive index.

A medium.
The material through which a wave travels is called the medium.

It refracts some and reflects some.
