What minimum separation between two objects a human eye would be able to resolve, if the eye pupil diameter is \(2 \mathrm{~mm}\) and the two objects are \(20 \mathrm{~m}\) away from the eye? (Assume, human eye to be equivalent to a convex lens and consider the average wave length of light as \(600 \mathrm{~nm}\) )
- A \(7.32 \mathrm{~mm}\)
- B \(8.72 \mathrm{~mm}\)
- C \(6.2 \mathrm{~mm}\)
- D \(4.71 \mathrm{~mm}\)
Answer & Solution
Correct Answer
(A) \(7.32 \mathrm{~mm}\)
Step-by-step Solution
Detailed explanation
Given, diameter of pupil, \(d=2 \mathrm{~mm}=2 \times 10^{-3} \mathrm{~m}\) \(D=20 \mathrm{~m}, \lambda=600 \mathrm{~nm}=6 \times 10^{-7} \mathrm{~m}\) For any aparture, limit of resolution is given as,…
