Electron microscopes differ from light microscopes because they use a beam of:
AElectrons
BUltraviolet
CRadio waves
DSound pulses
Answer & Solution
Correct answer: A. Electrons
1. A microscope resolves detail by the wavelength of whatever it sends through the sample.
2. Light microscopes send a beam of light.
3. Electron microscopes use a beam of electrons instead of a beam of light.
4. The far shorter wavelength of electrons is what lets them resolve organelles.
