change in direction of propagation of any wave as a result of its travelling at different speeds at different points along the wave front.
measurement of the focusing characteristics of an eye or eyes.
cause of refraction
The cause of the refraction of light is that light travels at different speeds in different media. This change in the speed of light when it moves from one medium to another causes it to bend. Refraction is caused due to the change in speed of light when it enters from one medium to another.
