A convex lens is made of 3 layers of glass of 3 different materials as in the figure.
A point object is placed on its axis. The number of images of the object are
- A 3
- B 4
- C 1
- D 2
Answer & Solution
Correct Answer
(C) 1
Step-by-step Solution
Detailed explanation
From the given diagram, we see that lenses \(L_{1}\) and \(L_{3}\) are identical but eontribute opposite sease, hence their combined effect of making image is ineffoctive. Hence, only lens \(L_{g}\) forms the image.
