Question

State Snell’s law of refraction of light. Write an

expression to relate refractive index of a medium with

speed of light in vacuum.

The refractive index of a medium ‘a’ with respect to

medium ‘b’ is 2/3 and the refractive index of medium

‘b’ with respect to medium ‘c’ is 4/3. Find the

refractive index of medium ‘c’ with respect to medium

‘a’.​

Answer 1

Answer:

Snell's law is

refractive index (n)= (sin i°\sin r°)

n= speed of light in vacuum (c)/speed of light in medium (v)
