Study Notes
Photoelectric Effect
- The primary outcome of the photoelectric effect is the ejection of electrons from a metal surface when it is exposed to electromagnetic radiation.
Energy Absorption
- The energy of the absorbed photon is transferred to the electron, allowing it to overcome the binding energy and escape from the metal surface.
Probability of Absorption
- The probability of photoelectric absorption is determined by the intensity of the incident radiation and the frequency of the incident radiation, not by its intensity.
Vacancy Formation
- When a vacancy is left in the atomic structure by the ejected electron, it can be filled by other electrons, resulting in a cascade of electrons moving to higher energy levels.
Electron Affected
- The electrons most affected by the probability of photoelectric absorption are the valence electrons, which are the outermost electrons of an atom.
