No refraction can occur either way!

The density. Refraction occurs at the boundary between two media of differing densities, such as air and water.
For refraction to occur, there must obviously be two different substances that are both transparent to the radiation or waves under consideration. Also, the two substances must have different indices of refraction.
Reflection happens only at the interface between two media, and two media with the same index of refraction act as if they were a single medium. Thus, at the interface between media with the same index of refraction, there is no reflection, and the ray keeps going straight. Continuing this line of thought, it is not surprising that we observe very little reflection at an interface between media with similar indices of refraction.
No refraction can occur either way!
For refraction to occur in a wave, the wave must enter a new medium at an angle.

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.
It is because of the change in velocity of light in two different media.
No
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........
