Multiple Choice

What is the main difference between a light microscope and an electron microscope in terms of the source used to magnify objects?

• Light microscope uses light, electron microscope uses electrons

• Light microscope uses electrons, electron microscope uses light

• Both use light

• Both use electrons

Multiple Choice

What is the main difference between a Scanning Electron Microscope (SEM) and a Transmission Electron Microscope (TEM)?

• SEM studies the surface of specimens, while TEM studies internal cell structures.
