COMEDK · Physics · 27. Dual Nature of Matter
The basic principle used behind the working of electron microscope is:
- A Wave nature of electrons.
- B Magnifying power of very thin aperture convex lenses.
- C Electrostatic field created by a beam of electrons.
- D Using charged mirrors to achieve the desired magnification.
Answer & Solution
Correct Answer
(A) Wave nature of electrons.
Step-by-step Solution
Detailed explanation
The working of an electron microscope is based on the wave nature of electrons. According to de Broglie's hypothesis, moving electrons behave as waves. The wavelength of these electron waves is much smaller than that of visible light, which allows for a much higher resolving…

- Given below are 2 statements: Assertion and Reason. Choose the correct option.
Assertion: When Molar conductivity for a strong electrolyte is plotted versus \(\sqrt{C}(\mathrm{~mol} / \mathrm{L})^{1 / 2}\), a straight line is obtained with intercept equal to Molar conductivity at infinite dilution for the electrolyte and Slope equal to \(-\mathrm{A}\). All electrolytes of a given type have the same \(\mathrm{A}\) value.
Reason: At infinite dilution, strong electrolytes of the same type will have different number of ions due to incomplete dissociation.COMEDK 2024 Medium - Heavy water isCOMEDK 2013 Easy
