Refraction occurs because waves move at different speeds in different bodies. Because a wave hits the other medium at an angle, part of the wave changes speed earlier than the rest, turning the waves. this is most obvious with light waves in water, but it happens with all types of waves in any change of medium.
Refraction of light occurs when it passes from one transparent medium to another one of a different optical density.
The major refracting interfaces in the eye are-
When light leaves a medium, and enters a less dense or more dense medium, it is refracted, because the speed of light changes.
Example: Light travelling in air moves at a speed of 3.0 x 108 metres per second. If the light is made to pass through water, which is denser than air, the speed of light slows down, and as a result it is refracted.
refraction occurs when a light ray passes from a rarer to denser medium or vice versa
Refraction occurs at the point where light passes from one transparent medium to another medium of a different density.

Refraction occurs when light encounters a medium with different optical density.
The bending of light when it travels from one medium to another is called refraction.

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........
refraction
The angle if refraction also increases.
Refraction phenomenon
Prisms create spectrum of colors by the cause 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.
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.
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.
