Question

state and explain Snell's law​

Answer 1

$<b>$
Hello !!

The Answer is:

Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.

Answer 2

Heya,

Here is your answer...

↓↓↓↓↓↓↓↓↓↓

There is a law that relates the size of angle of refraction r to the angle of incidence i.

This is Snell's law.

It also involves the refractive index, since the greater the refractive index, the more a Ray is bent.

The law is written in the form of an equation:

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

The pic attached above is a worked example of Snell's law...
