PhysicsEasysingle choice

A converging lens forms a real image $I$ of an object on its principal axis. A rectangular slab of refractive index $μ$ and thickness $x$ is introduced between $I$ and the lens, $I$ will move

Options:

Answer:

Solution:

Due to insertion of slab, the optical path increases by $x / μ$ , where $x$ is thickness of slab. Therefore the converging point will shift away by $[x - \frac{x}{μ}] = x (1 - \frac{1}{μ})$ .
