Question

deffine the refraction​

Answer 1

Explanation:

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed.

Answer 2

Answer:

Refraction:-The change in the direction of a wave

passing from one medium to another.

or

It is the bending of light as it passes from one substance to another.
