Question

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`

Answer 1

Correct Answer - 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`
