If numerical aperture of a microscope is increased, then its

A

resolving power decreases

B

limit of resoltuion decreases

C

resolving power remains constant

D

limit off resolution increases

Text Solution

Verified by Experts

The correct Answer is:
B
for a microscope, limit of resolution, `x=(lamda_(0))/(2(NA))` where NA is the numerical aperture of the microscope
`therefore` If NA is increased, x is decreased.
