Electron microscopes have a resolution advantage over light microscopes because
A) electron microscopes allow the viewer to examine living cells.
B) electron microscope lenses have a larger numerical aperture.
C) electron microscopes are easier to use.
D) the wavelength of electrons is shorter than that of light.

Question

Quizplus · Accepted Answer

The wavelength of electrons is shorter than that of light, allowing electron microscopes to achieve greater resolution. Electrons have much shorter wavelengths than visible light, which can only be focused through a lens with a limited numerical aperture.
