Electron microscope has a high resolution power. This is due to
Updated On: Aug 4, 2024
- Electromagnetic lenses
- Very low wavelength of electron beam
- Low wavelength of light source used
- High numerical aperture of glass lenses used.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Electron microscope has a high resolution power. This is due to very low wavelength of electron beam (0.005 mu) of the electron beam used as light source. It is produced when a metal filament is heated in a vaccum tube at high temperature, i.e., 50,000 volts.

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
