Photons with energies lower than the electron binding power could also be absorbed or scattered but is not going to photoionize the atom or ion. For instance, to ionize hydrogen, photons need an vitality greater than 13.6 electronvolts (the Rydberg vitality), which corresponds to a wavelength of 91.2 nm. Planck fixed and ν is the frequency of the photon. This system defines the photoelectric effect. Not each photon which encounters an atom or ion will photoionize it. The chance of photoionizatio...
