At what distance eye E will observe the fourth image (after four refractions from plane surfaces) of object O from itself.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Total shift `=(1-1/mu_1)t_1+(1-1/mu_2)t_2`
`=(1-2/3)10+(1-1/2)10`
`=25/3 cm`
`:.` Image distance `=50-25/3=125/3 cm`
