Why do electron microscopes provide much greater resolving power than light microscopes?
A)because more electrical power is involved in running an electron microscope
B)because the wavelength of an electron is much lower than that of visible light
C)because the wavelength of an electron is much higher than that of visible light
D)because the numerical aperture is much larger in electron microscopes
E)because the numerical aperture is much smaller in electron microscopes

Question

Quizplus · Accepted Answer

The resolving power of a microscope is inversely proportional to the wavelength of the radiation used in it. The wavelength of an electron is much lower than that of visible light, so electrons can be used to provide much greater resolving power than light microscopes.
