SEM and TEM

What is the basic principle of Optical Microscopy?

• To use visible light to magnify small objects

• To use ultraviolet light to magnify small objects

• To use infrared light to magnify small objects

• To use X-rays to magnify small objects

Name one type of Electron Microscopy.

• Ultraviolet Microscopy

• Transmission Electron Microscopy (TEM)

• X-ray Microscopy

• Scanning Electron Microscopy (SEM)

What does SEM stand for in the field of microscopy?

• Small Electronic Magnifier

• Science Experiment Machine

• Scanning Electron Microscopy

• Super Exciting Microscope

What does TEM stand for in the field of microscopy?

• Transmission Electron Microscopy

• Tropical Ecology Mapping

• Temperature Emission Monitor

• Total Energy Measurement

How are SEM and TEM different from each other?

• SEM uses a magnetic field to scan the surface of a sample, while TEM uses a laser beam to create an image

• SEM uses sound waves to scan the surface of a sample, while TEM uses radio waves to create an image

• SEM uses visible light to scan the surface of a sample, while TEM uses X-rays to create an image

• SEM uses a focused beam of electrons to scan the surface of a sample, while TEM transmits electrons through a thin specimen to create an image.
