Question

Which of the following is true for rays coming from infinity?

• A. Two images are formed
• B. Continuous image is formed between focal points of upper and lower lens
• C. One image is formed
• D. None of the above

Answer 1

Answer: (A)

Two images are formed

Answer 2

Since, lens is made of two layers of different refractive indices, for a given wavelength of light it will have two focal lengths or will form two images at two different points as there are $\mu s$ as $\frac{1}{f}\propto (\mu -1)$
