Question

Refractive index of diamond with respect length is 1.6 and absolute refractive index of glass is 1.5 find absolute refractive index of diamond

Answer 1

Refractive index of diamond with respect to glass is 1.6

Medium 1 = glass

Medium 2 = diamond

Medium 3 = air

n3 = 1

n13 = 1.5 = n1/n3

Implies, n1 = 1.5

n21 = 1.6 = n2/n1

Therefore, n2 = 1.6 x n1

= 1.6 x 1.5

= 2.4

Therefore, n23 = n2/n3

= 2.4/1

= 2.4
