Question

What are the laws of refractions?​

Answer 1

Answer:

Explanation:

their are only two laws

1 ) incident ray is always equal to reflected ray . (i = r )

2) incident ray, reflected ray and the normal all lying in the same plane are at equal distance from each other

Answer 2

The 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.

• Snell's law of refraction: The ratio of the sine of angle of refraction is a constant, for the light of a given colour and for the given pair of media.

sin i / sin r = constant
