Question

How to calculate refractive index applying snell's law?

Answer 1

$snell \: law \: = \sin(i ) \div \sin(r)$

where i= angle of incidence

and r= angle of refraction

for calculating refractive index, we should know i and r....and...

the values of their respective sines

On putting the values in the formula we can easily find the refractive index

Answer 2

Answer:

using speed as sin i and time as sinx
