Q32 of 117 Page 10

The refractive index of dense flint glass is 1.65, and for alcohol it is 1.36, with respect to air. What is the refractive index of dense flint glass with respect to alcohol?

Refractive index of dense flint glass w.r.t. air, n1 = 1.65
Refractive index of alcohol w.r.t. air, n2 = 1.36
Refractive index of dense flint glass with respect to alcohol is
= = 1.21.
The refractive index of dense flint glass with respect to alcohol = 1.21.
