Question

what is snell's law? And give its expression

Answer 1

snell's law is an formula used to describe relationship between angle of incidence and angle of refraction

                        expression:
                                              sinФ1/sinФ2=v1/v2=n1/n2

Answer 2

Snell's law 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 a given colour and for the given pair of media. Its expression is $\frac{sin\ i}{sin\ r}=\mu$

Explanation:

The degree of refraction and the relationship between the angle of incidence, the angle of refraction, and the refractive indices of a specific pair of media are provided by Snell's law. We are aware that when light moves from one medium to another, it is refracted or bent. The bend's degree can be predicted by Snell's law. Another name for it is the law of refraction. The law of refraction, sometimes known as Snell's law, was discovered by Willebrord Snell in 1621.

According to Snell's law, "For light of a particular colour and for the given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant." Snell's law is phrased as follows:

$\frac{sin\ i}{sin\ r}=\mu$

where 'i' denotes the incidence angle and 'r' is the refraction angle. The refractive index of the second medium with respect to the first is this constant value.
