A ray of light incident ray on the surface of a medium at an angle 45° and is refracted in the medium at an angle 30° . what is the velocity of light in the medium? |

Answer» Explanation: REFRACTIVE INDEX, n=sinrsini=vc Hence, SPEED of sound in the medium v=sinicsinr=sin45∘3×108×sin30∘ v=23×108m/s v=2.12×108m/s |
