Question

write down the laws of refraction​

Answer 1

Answer:

Laws of Refraction

1. 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.

2. 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 Snell’s law of refraction.

N = sin i/ sin r

This constant is also called the refractive index of the second medium with respect to the first.

Answer 2

Answer:

Laws of refraction state that: The incident ray, reflected ray and the normal, to the interface of any two given mediums, all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant. This is also known as Snell's law of refraction.
