1.	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 θtI have been asked this question during an online interview.My doubt stems from Snell Law and Critical Angle in portion EM Wave Propagation of Electromagnetic Theory
Answer» 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.
