Question

Refractive Index of a transparent fluid with respect to air
is 1.40 calculate the refractive index of air with respect that fluid​

Answer 1

Answer:

Refractive index of medium 1 with respect to medium 2 is given by

m = n1/n2

n - refractive index

Other way is, refractive index of 2 with respect to 1 is

M = n2/n1 = 1/m

Therefore refractive index of air with respect to fluid is

N = 1/1.4 = 0.714
