A person is viewing two red dots at a distance of `1000 m`. What should be the minimum distance between dots so the his eye can resolce two dots separately.
`("take" : lambda_(red) + 700 nm, "pupil dia" = 2.5 mm)`

Two parallel pillars are 11 km away from an observer. The minimum distance between the pillars so that they can be seen separately will be

The diameter of the pupil of human eye is 2.5 mm. Assuming the wavelength of light used is 5000 Å. What must be the minimum distance between two point like objects to be seen clearly if they are at a distance of 5 m from the eye ?
