Question

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

Answer 1

R.I. of dense flint glass w.r.t. air is = ^aμ_fg = 1.65

R.I. of alcohol w.r.t. air is = ^aμ_al = 1.36

So, R.I. of flint glass w.r.t. alcohol is,

^alμ_fg = (^aμ_fg)/(^aμ_al) = 1.65/1.36 = 1.21
