Question

Define snells law.write an expression to relate refractive index of a medium with speed of light in a vacuum

Answer 1

Snell's law is n1 sin i=sin r.
n1 is the speed of light in first medium .
n2 is the speed of light in 2nd medium
i is angle of incidence
r is angle of refraction


hope it helps u.
please mark me as brain list.

Answer 2

✨✔️✔️HERE IS YOUR ANSWER....

✨The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given colour and for the given pair of media. This law is known as Snell’s Law of Refraction.

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

✨
$refractive \: index = \frac{speed \: of \: light \: in \: vacuum}{speed \: of \: light \:in \: medium}$
