which three of the following are associated with electron microscopes?

• electron beams
• glass lenses
• electromagnets
• light rays
• high vacuum

Explanation:

Electron microscopes use electron beams instead of light rays for imaging, so electron beams are associated and light rays are not. They use electromagnets (not glass lenses) to focus the electron beam. A high vacuum is required to prevent electron scattering, making it a necessary component.

Answer:

• Electron beams
• Electromagnets
• High vacuum
