Question

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

Answer 1

Answer:

Refractive index of diamond with respect to glass n

dg

=1.6

Refractive index of glass n

g

=1.5

Refractive index of diamond n

d

=?

Refractive index of diamond with respect to glass n

dg

=

n

g

n

d

So,the refractive index of diamond n

d

=n

dg

×n

g

or, n

d

=1.6×1.5=2.4

hence,the refractive index of diamond is 2.4
