Electron microscopes have a much better resolving power when compared to light microscopes because electrons _____.
A)are invisible to the eye
B)have longer wavelengths than visible light rays
C)have shorter wavelengths than visible light rays
D)are negatively charged

Question

Quizplus · Accepted Answer

The resolving power of a microscope is defined as the ability of the microscope to distinguish two closely positioned objects as separate entities. The resolving power of a microscope depends on the wavelength of the radiation used for imaging. Electrons have much shorter wavelengths (about 0.005 nm) compared to visible light (about 400-700 nm). Hence, electron microscopes have a much better resolving power than light microscopes.
