In a vessel two insoluble liquids are filled as shown in the figure. The effective refractive index of the combination for normal view is

A

`1.33`

B

`1.5`

C

`1.67`

D

`1.4`

Text Solution

Verified by Experts

The correct Answer is:
D
`d_("APP") = (d_1)/(mu_1) + (d_2)/(mu_2) = (d + d_2)/(v_(eff))`
`implies v_(eff) = (d_1 + d_2)/((d_1)/(mu_1) + (d_2)/(mu_2))`
