Question

Snell's law is

a) sin r/sin I=μ
b) sin μ/sin l=r
c) sin μ/sin r=i
d) sin i/sin г=μ​

Answer 1

The correct form of Snell's law is:

a) sin r / sin I = u

where n is the refractive index of the medium.

It relates the angle of incidence I and angle of refraction r of a light ray passing through two media with different refractive indices.
