The wavelength of electrons used in electron microscopes is much shorter than that of visible light. What does this result in?
Lower resolution
Higher resolution
Reduced magnification
Inverted images
What is the purpose of the objective lens in a Transmission Electron Microscope
To focus the electron beam
To magnify the image
To control specimen illumination
To scan the specimen surface
What is the purpose of the vacuum environment in an electron microscope?
To increase electron wavelength
To reduce air resistance
to increase electron scattering.
to reduce electron scattering.
What is the primary factor influencing the energy of X-rays produced in a continuous X-ray spectrum?
Atomic number of the target material
Current in the X-ray tube
Voltage applied to the X-ray tube
Temperature of the X-ray tube
In characteristic X-ray spectra, the energy of emitted X-rays is determined by:
Voltage applied to the X-ray tube
Atomic number of the target material
Current in the X-ray tube
Temperature of the X-ray tube
What happens to the intensity of characteristic X-rays as the atomic number of the target material increases?
Increases
Decreases
Remains constant
increases and then decreases
In the production of characteristic X-rays, what is the role of the incident X-ray photon?
It knocks out an inner-shell electron.
It scatters off an outer-shell electron.
It interacts with a proton in the nucleus.
It annihilates an electron-positron pair.
