Question

what is refraction?plsssssss tell for class 7

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.

Answer 2

There is a change in the direction of the speed of the wave reaching from one medium to another, which is called refraction.When light travels diagonally from one medium to another, the direction of its transmission from the other medium changes. This is called refraction
