The refractive index of water, glass and diamond are `1.33`, `1.50`, `2.40` respectively. The refractive index of diamond relative to water and of glass relative of diamond, respectively are nearly

Options

A. 1.804, 0.605
B. 0.554, 0.625
C. 1.8, 1.6
D. 0.554, 1.6

Answer

A

Explanation

`._(w)mu_(d) = (mu_(d))/(mu_(w)) = (2.4)/(1.33) = 1.804`
and `._(d)mu_(g) = (mu_(g))/(mu_(d)) = (1.5)/(2.4) = 0.625`
