  1. A only 1
  2. B 2
  3. C 2.5
  4. D 5
Verified Solution

Answer & Solution

Correct Answer

(B) 2

Step-by-step Solution

Detailed explanation

Given materials of \(\mu_1\) and \(\mu_2\) refractive indices are used to form lens. So, corresponding to these, there are two focal lengths of lens. Thus, the number of images formed will be 2 .
