JEE Main 2005 Physics question
Two point white dots are 1 mm apart on a black paper. They are viewed by eye of pupil diameter 3 mm. Approximately, what is the maximum distance at which these dots can be resolved by the eye? [ Take wavelength of light = 500 nm ]
Answer: (1)
Solution
Limit of resolution \frac{1.22λ}{d}\frac{1.22×5×10^{-7}}{3×10^{-3}}$
