Question

Refractive indices of water and glass are 4/3 and 3/2 respectively. A light ray travelling in water

is incident on water glass interface at 45. What is the angle of refraction? (Take, sin 38.9 =

0.6284)​

Answer 1

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
