Refraction
when light travels from air to a transparent object it is travelling trough a different media
of different densities therefore it slows down.
If the ray of light enters a new medium at an angle to the normal(line drawn to 90 degrees)
then one side of the beam of light will change speed slightly before the other side making it
change direction

actually light is another type of wave
which travel in ether medium which is disturbed by the atom of matter so disturbance causes bend of light.....
No refraction can occur either way!
For refraction to occur in a wave, the wave must enter a new medium at an angle.
More details!
Refraction occurs for any waves, where there's a change in the medium.
The density. Refraction occurs at the boundary between two media of differing densities, such as air and water.
Yes, it is true.
No
It is because of the change in velocity of light in two different media.
the difference is transmission occur in same medium,but refraction occurs whn 2 medias are there,its actually bending of light at interface of 2 medias
one is refraction i can assure you that.
The definition of critical angle is the angle of incidence that refraction can still occur.
Refraction is the bending of the rays of light when it travels from one medium to another... For refraction to occur there should be some difference in the refractive index of the materials.... Refraction can also occur in Opaque medium........
