- A
- B Infinity
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
For the first lens f1=+10 u1=-30 Applying the Lens formula, 1f=1v-1u 1v1=1f1+1u1 1v1=110-130=115 ⇒v1=15 cm, that means for the second lens objective distance u2=15-5=10 cm So that light rays appear to be converging to focus so after refraction they will be…
