Question

Which of the following is Shell’s law. [ ]
a) n1sin i = sin r/ n2
b) n1/n2= sin r / sin i
c) n2 / n1= sin r / sin 1
d) n2sin i = constant

Answer 1

option B is correct.h ope it helps you

Answer 2

Dear Student,

◆ Answer -

(b) n1 / n2 = sinr / sini

● Explaination -

Snell's law gives relationship between refractive index, angle of incidence and angle of refraction.

n = sini / sinr

Here, refractive index means that of 2nd medium wrt 1st medium.

n21 = sini / sinr

n2 / n1 = sini / sinr

n1 / n2 = sinr / sini

Hope that cleared your concepts...
