⬛ Which of the following is Shell's law.

a) n, sin i= sin r/n,

b)n,/n, =sin r/sini

c)n/n, = sin r/sini

d) n, sin i=constant

$\mathfrak{\huge{\underline{\underline{\green{Answer:-}}}}}$

✒ Option (b) $\underline {\dfrac{n1}{n2} = \dfrac{sini}{sinr}}$

$\mathcal{\huge{\underline{\underline{\pink{Solution:-}}}}}$

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

➡$\boxed{\red{\dfrac{n1}{n2} = \dfrac{sini}{sinr}}}$ ✅
