Question

write three laws of snell​

Answer 1

Answer:

snell law is used in physics in light

Explanation:

sin  i =sin r

sin i/sin r=constant

Answer 2

Explanation:

Snell’s Law

It gives the amount of bending of light rays. It also determines the relationship between the angle of incidence, the angle of refraction and relative indices of a given pair of media. It is the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant for the light of given color and for the given pair of media.

Laws of Refraction

The angle of incidence is the angle between the incident ray and the normal; denoted as ‘i’. The angle of refraction is the angle between the refracted ray and the normal; denoted as ‘r’. 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.
