Question

Consider three converging lenses L1,L2 and L3 having identical geometrical construction. The index of refraction of L1 and L2 are μ1and μ2 respectively. The upper half of the lens L3 has a refractive index μ1 and lower half has μ2. A point object O is imaged at O1 by the lens L1 and O2 by the lens L2 placed in same position. If L3is placed at the same place,

  1. there will be an image at O1
  2. there will be an image at O2
  3. The only image will form somewhere between O1 and O2
  4. The only image will form away from O2

A
there will be an image at O1
B
there will be an image at O2
C
The only image will form somewhere between O1 and O2
D
The only image will form away from O2
Solution
Verified by Toppr

The two halves of the lens L3 will act as separate lenses and each of them will form its own image.Thus there will be two images at O1&O2 respectively.

Q3
Consider three converging lenses L1,L2 and L3 having identical geometrical construction. The refractive indices of L1 and L2 are μ1 and μ2 respectively. The upper half of the lens L3 has refractive index μ1 and the lower half has μ2 as shown in the figure. A point object O has an image at O1 by the lens L1 and at O2 by the lens L2 placed in the same position. If L3 is placed at the same place:
