What is a characteristic photon?
A photon that is emitted by an outer shell electron
What determines the likelihood of a photoelectric interaction?
The kVp level and the electron-binding energy of the atom
Study Notes
Photoelectric Interaction
- During a photoelectric interaction, a photon (light particle) collides with a bound electron in a material, transferring its energy to the electron.
- The energy from the photon is absorbed by the electron, causing it to be ejected from its atom or molecule.
Characteristics of Photons
- A characteristic photon is a photon with a specific energy and frequency, which determines its ability to interact with electrons.
- The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength.
Determinants of Photoelectric Interaction
- The likelihood of a photoelectric interaction is determined by the energy of the photon and the binding energy of the electron.
- A photon with energy greater than the binding energy of the electron can eject the electron, resulting in a photoelectric interaction.
