Question

In Figure, a point object O is placed in air. A spherical boundary separates two media. Ab is the principall axis. The refractive index above AB is 1.6 and below AB is 2.0. The separation between the images formed due to refraction at a the spherical surface is (assume the radius of curvature (R) to be 1 unit)

A. 12m
B. 20m
C. 14m
D. 10m

Answer 1

Correct Answer - a.
Use refraction formulae separately, that is for air and `mu=1.6,` and for air and `mu=2.0` and positions of the two images.
