Question

The Snell’s law is given by (a) N1 sin θi = N2 sin θt (b) N2 sin θi = N1 sin θt (c) sin θi = sin θt (d) N1 cos θi = N2 cos θt I have been asked this question during an online interview.

Answer 1

The correct choice is (a) N1 sin θi = N2 sin θt For explanation: The Snell law states that in an oblique medium, the product of the refractive index and sine of incidence angle in medium 1 is same as that of medium 2. Thus it is given by N1 sin θi = N2 sin θt.
