Question

refraction ??????????​

Answer 1

Refraction

• the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.
• 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.

Answer 2

Refraction is the bending of a light or sound wave, or the way the light bends when entering the eye to form an image on the retina. An example of refraction is a bending of the sun's rays as they enter raindrops, forming a rainbow. An example of refraction is a prism.. ..

Or

Refraction is the phenomenon of bending of light at the boundary of two mediums. Refraction is caused due to the change in speed of light when it enters from one medium to another. .when light goes from water to air it bends away from the normal because three is an increase in speed of light..
