Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
In the light of the above statements, choose the correct answer from the options given below :
| Assertion A : | An electron microscope can achieve better resolving power than an optical microscope. |
| Reason R : | The de Broglie's wavelength of the electrons emitted from an electron gun is much less than wavelength of visible light. |
Official answer
(1)
Both $\displaystyle \mathbf{A}$ and $\displaystyle \mathbf{R}$ are true and $\displaystyle \mathbf{R}$ is the correct explanation of $\displaystyle \mathbf{A}$.
