NEET Physics Lenses MCQ Question
The figure shows two converging lenses. The light rays are incident parallel to principal axis on first lens as shown. The distance between the lenses so that the emergent rays are also parallel to principal axis is
10 cm
20 cm
35 cm
50 cm
Correct Answer
Detailed Explanation
For the emergent rays to be parallel, the lenses must be separated by the sum of their focal lengths. This ensures that the rays converge at the focal point of the second lens.
