Question

14. What is refractive index? What is its unit? 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 of dense flint glass with to alcohol?

Answer 1

x is the refractive index here

x of glass w.r.t. air=1.65=x1

x of alcohol w.r.t. air=1.36=x2

now , x of glass w.r.t. alcohol is = x1/x2

= 1.65/1.36 = 1.21 will be the ans.

Answer 2

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

ANSWER...

x of glass w.r.t.

air=1.65=x1

x of alcohol w.r.t.

air=1.36=x2

x of glass w.r.t. alcohol is = x1/x2

= 1.65/1.36

= 1.21

will be the ans.
