Question

What is snell's law?

Answer 1

Snell's law:

"The proportion of the sine of the angle of incidence to the sine of the angle of refraction remains a constant, considering light of a particular color as well as for the specific combination of media," according to Snell's law.

Mathematical representation:

${\mathrm{n}}_1{\mathrm{sin\theta }}_1={\mathrm{n}}_2{\mathrm{sin\theta }}_2$

Here,

${\mathrm{n}}_1$ is the incident index of 1st medium.

${\mathrm{n}}_2$ is the refracted index of 2nd medium.

${\mathrm{\theta }}_1$ is the angle of incidence.

${\mathrm{\theta }}_2$ is the angle refraction.
