For the same objective . what is the ratio of the least separation between tow points to be distinguished by a microscope for light of 5000Å and electrons accelerated through 100V used as an illuminating substance?
Text Solution
Verified by ExpertsThe correct answer is:
C
The limit of resolution of a microscope is 
where 
is the angle of cone of light rays entering the objective of the microscope.
Here, 
For electrons accelerated through 100 V, de Broglie wavelength,
As 
is same in the two cases, therefore,
