The resolving power of electron microscope is higher that that of an optical microscope because the wavelength of electrons is ……. Than the wavelength of visible light.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer

C

Explanation

The wavelength of wave associated with electrons (de Broglie waves) is less than that of visible light. We know that resolving power is inversely proportional to wavelength of wave used in microscope. Therefore, the resolving power of an electron microscope is higher than that of an optical microscope.
