Question

Refractive index of diamond with respect to glass is 1.6 and absolute refractive index of glass is 1.5. Find out the absolute refractive index of diamond.

Answer 1

Given:
Refractive Index of glass (n_g) = 1.5

Refractive Index of diamond with respect to glass (n_dg) = 1.6

Refractive index of diamond with respect to glass =

`("Refractive index of diamond"  ("n"_"d"))/("Refractive index of glass")`

`1.6 = "n"_"d"/1.5`

n_d = 1.5 × 1.6

= 2.4

Hence, the absolute refractive index of diamond is 2.4.
