Q.
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
Explanation
(a) 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
$\frac{1}{f} \propto (\mu - 1)$
