The diameter of human eye lens is `2 mm`. What should be the minimum separation between two points situated at `50 m` from eye, to resolve tham. Take wavelength of light `= 5000 Å`.

A

2.32 m

B

4.28 mm

C

1.25 cm

D

12.48 cm

Text Solution

Verified by Experts

The correct Answer is:
C
For the aparture , limit of resolution -
`y/D le lambda/d rArr y le (lambdaD)/d`
`y le (5xx10^(-7))/(2xx10^(-3))xx50 le 1.25` cm
