A converging lens forms a real image of an object on its principal axis. A rectangular slab of refractive index (\mu) and thickness is introduced between and the lens, will move
Options
- Atowards the lens ((\mu-1) x)
- Btowards the lens by (\left(1-\frac{1}{\mu}\right) x)
- Caway from the lens by ((\mu-1) x)
- Daway from the lens by (\left(1-\frac{1}{\mu}\right) x).
Correct answer
D. away from the lens by (\left(1-\frac{1}{\mu}\right) x).
Step-by-step solution
Due to insertion of slab, the optical path increases by , where is thickness of slab. Therefore the converging point will shift away by
.
