What is the explanation for how a modern transmission electron microscope (TEM) can achieve a resolution of about 0.2 nanometres, whereas a standard light microscope has a maximum resolution of about 200 nanometres?
A) Glass lenses in light microscopes refract light, which reduces resolution.
B) Contrast is enhanced by staining with atoms of heavy metal.
C) Electron beams have much shorter wavelengths than visible light.
D) The electron microscope has a much greater ratio of image size to real size.

Question

Quizplus · Accepted Answer

Electron beams have much shorter wavelengths than visible light, which enables the modern transmission electron microscope to achieve a resolution of about 0.2 nanometres.

Answer: A
 Glass lenses in light microscopes refract light, which reduces the resolving power, resulting in a maximum resolution of about 200 nanometres.
