Science behind Refraction:
Snell’s Law, which can be stated as:
nA Sinθ A = nB Sinθ B
As light rays pass from one medium to another, they change direction in order to follow the quickest paths through the system.
Refraction
Definition- the bending of a wave as the wave passes between two substances in which the speed of the wave differs
We use refraction to help us see through types of glasses and binoculars. It also helps us see the chemical properties of planets.
