Two points separated by a distance of 0.1 mm can just be resolved in a microscope when a light of wavelength 6000 Å is used. If the light of wavelength 4800 Å is used this limit of resolution becomes :-

Options

A. 0.08 mm
B. 0.10 mm
C. 0.12 mm
D. 0.06 mm

Answer

A

Explanation

`d_(min) prop lambda rArr (d_(1))/(d_(2)) = (lambda_(1))/(lambda_(2)) rArr (0.1)/(d_(2)0 = (6000)/(4800)`
`d_(2) = 0.08 ` mn.
