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

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

Options

  1. ATwo images are formed
  2. BContinuous image is formed between focal points of upper and lower lens
  3. COne image is formed
  4. DNone of the above

Correct answer

A. Two images are formed

Step-by-step 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 μ\mu 's as 1f∝(μ−1)\frac{1}{f} \propto(\mu-1)
