Two points separated by a distance of 0....

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

A

0.8 mm

B

0.12 mm

C

0.1 mm

D

0.08 mm

Text Solution

Verified by Experts

The correct Answer is:
D

New limit of resolution `=(4800)/(6000)xx0.1 mm=0.08mm`
