As shown in the figure, region BCDEF and ABFG are of refractive index `2.0 and 1.5` respectively. A particle O is kept at the mid of DH. Image of the object as seen by the eye is at a distance

A

`10 cm` from point D

B

`22.5 cm` from point D

C

`30 cm` from point D

D

`20 cm` from point D

Text Solution

Verified by Experts

The correct Answer is:
A
Apply `(mu_2)/v-(mu_1)/v=(mu_2-mu_1)/R`
We get `1/v-2/(-10)=(1-2)/(-10)`
Solving we get, `v=-10 cm`
