What is an electron microscope?
Q: What is an electron microscope?
A: An electron microscope is a scientific instrument that uses a beam of electrons to examine objects on a very fine scale.
Q: How do electron microscopes achieve higher magnification than optical microscopes?
A: Electrons have a smaller wavelength than light, so they can achieve a higher magnification.
Q: What is the maximum magnification achievable with an electron microscope?
A: The maximum magnification achievable with an electron microscope is typically around 1,000 times smaller than that seen in an optical microscope.
Q: How are the outlines of objects revealed in an electron microscope?
A: The outline of objects in an electron microscope is revealed by the flow of electrons.
Q: What is used to convert the outline of objects in an electron microscope into a picture that people can see?
A: The outline of objects in an electron microscope is changed into a picture using visible light.
Q: When and where were electron microscopes invented?
A: Electron microscopes were invented in Germany in the 1930s.
Q: What limits the maximum magnification possible with an optical microscope?
A: The wavelength of light limits the maximum magnification possible with an optical microscope.
