In the figure, a point object O is placed in air. A spherical boundry separates two media of radius of curvature `1.0 m.` AB is principal axis. The separation between the images formed due to refraction at spherical surface is

A

`12 m`

B

`20 m`

C

`14 m`

D

`10 m`

Text Solution

Verified by Experts

The correct Answer is:
A
`1.6/(v_1)-1.0/(-2)=(1.6-1.0)/(+10)`
rArr `v_1=16 cm`
`2.0/(v_2)-1.0/(-2)=(2.0-1.0)/(+10)`
`:. v_2=4m`
`I_2I_2=v_1-v_2`
`=12 cm`
