WebIonospheric Physics. The ionosphere is created by the ionization of the neutral atoms and molecules of the atmosphere. There are two basic requirements for the formation of an … WebMost of the electrical activity in the ionosphere is produced by photoionization (ionization caused by light energy). Photons of short wavelength (that is, of high frequency) are absorbed by atmospheric gases. A portion of the energy is used to eject an electron, converting a neutral atom or molecule to a pair of charged species—an electron, which is …
