Question

mention the laws of retraction with diagram​

Answer 1

Answer:

Laws of refraction of light are

The incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence, all lie in the same plane.

The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given color and for the given pair of media. This law is also known as Snells law of refraction.

#ANSWERWITHQUALITY & #BAL

Answer 2

1. Angle of incidence is equal to angle of reflection.
2. Incident ray, reflected ray and normal ray perpendicular to surface lies on same plane.
