Q154 / 200 · JIPMER 2008 · Physics

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

Correct answer
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

Solution

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 $\frac{1}{f} \propto(\mu-1)$

Hence, the correct answer is option: 'A'.
