Figure shows figure three transparent medi of refractive indices `mu_1, mu_2 and mu_3`. A point object O is placed in the medium `mu_2`. If the entire medium on the right of the spherical surface has refractive index `mu_1`, the image forms at O. If this entire medium has refractive index `mu_2` the image form at O''. In the situation shown

Options

A. the image forms between and `O'` and `O' '`
B. the image forms to the left of `O'`
C. the image forms to the right of `O' '`
D. 2 images, one at `O'` and the other at `O' '`

Answer

D

Explanation

Two images will be formed one due to `mu_2` and `mu_3` and another due to `mu_3` and `mu_1`
