When a ray of light passes from one medium to other, it bends from its path. This phenomenon of bending of light is called as refraction of light. There are two laws of refraction one is the incident ray, the refracted ray and the normal at the point of incidence all lie in the same plane and the other one is the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant for a given medium. Can you pass this test on the refraction of light?
