Question

what is refraction of light?​

Answer 1

Explanation:

change in direction of wave passing from one medium to another or form a gradual change in medium. commonly observed in sound and water wave.

Answer 2

Answer:

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.

Snell's law

                $n_{1} sin$θ₁=$n_{2} sin$θ₂

$n_{1}=$  incident index

$n_{2} =$  refracted index

θ₁ =  incident angle

θ₂ = refracted angle
