Thank yo

Answer 2

Answer:

The ratio of sine of angle of incidence to the sine of angle of refraction for light to given colour is constant for a given pair of media is called Snell's law.

$it \: is \: expressed \: as...$

$\frac{ \sin \: i }{ \sin \: r } = n$

$this \: constant \: is \: known \: as \\ refractive \: index.$
