Question

Whenever the light enters from one medium to another ,it gets refracted. Why?

Answer 1

Hii dear here is your answer


Waves. Refraction is an effect that occurs when a light wave, incident atan angle away from the normal, passes a boundary from one mediuminto another in which there is a change in velocity of the light. ... The wavelength decreases as the light enters the medium and the light wave changes direction..


Hope it's help u

Answer 2

speed of light is different in different medium generally the medium with low refractive index have higher speed of light...
