Question

4) If the absolute refractive index
of glass is 1.5. then the velocity of light in
the glass is. choose the correctt option​

Answer 1

Refractive index of diamond with respect to glass ndg​=1.6

Refractive index of glass ng​=1.5

Refractive index of diamond nd​=?

Refractive index of diamond with respect to glass  ndg​=ng​nd​​

So,the  refractive index of diamond nd​=ndg​×ng​

or, nd​=1.6×1.5=2.4

hence,the refractive index of diamond is 2.4
