Question

5. If the absolute refractive indices of two mediums 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
4/3 and that of glass is 3/2. Find the refraction index of
glass relative to water.​

Answer 1

Answer:

9/8

Explanation:

formula :- 1n2 × 2n1 = 1 orelse, n21= n2/n1

problem explanation ,

let n= refractive index

given absolute n of water= 4/3

absolute n of glass= 3/2 then,

n of glass relative to water= 3/2×3/4

= 9/8
