Question

if the absolute refractive index of two medium be N1 and N2 respectively determine the formula for refractive index of second medium relative to the first medium if the absolute refractive index of water is 4 by 3 and that of Glass is 3 by 2 find the refractive index of Glass relative to water​

Answer 1

Answer:

N21= N2/N1

9/8

Explanation:

N21=3/2×3/4

N21= 9/8
