Show Answer
Solution:
Ans. }
The resolving power of an electron microscope is much better than that of optical microscope.
[CBSE Marking Scheme 2014]
Detailed Answer :
De-Broglie wavelength of an electron
Accelerated pôtential
Hence,
Resolving Power of Microscope
From the formula, it is clear that resolving power increases as wavelength decreases keeping other factors as constant.
Wavelength of yellow light
