With a transmission electron microscope, a beam of electrons with what property compared to visible light is passed through a thinly sliced specimen?
Correct Answer
shorter wavelengths
Explanation
The transmission electron microscope (TEM) uses a beam of electrons that travel in shorter wavelengths than photons in visible light. These shorter wavelengths provide much greater resolution and magnification than any light microscope can achieve. The electrons are passed through a thinly sliced specimen within a vacuum and focused with electromagnets.
