InterviewSolution

1.	If numerical aperture of a microscope is increased, then itsA. resolving power remanis constantB. resolving power becomes zeroC. limit of resolution is decreasedD. limit of resolution is increased
Answer» Correct Answer - C Resolving limit of microscope is given by `RL=(lamda)/(2musinalpha)` where, `musinalpha` is called numerical aperture [NA] and `lamda` = wavelenghth of light. `:.RL=(lamda)/(2(NA))` Hence, if numerical aperture of a microscope is increased, then its limit of resolution is decreased.
