Incident electromagnetic radiation
WebElectromagnetic radiation is an electric and magnetic disturbance traveling through space at the speed of light (2.998 × 108 m/s). It contains neither mass nor charge but travels in packets of radiant energy called photons, or quanta.

WebINTRODUCTION. The energy quantization of electromagnetic radiation in general, and of light in particular, is expressed in the famous relation. (1) E = h f, where E is the energy of the radiation, f is its frequency, and h is Planck's constant (6.63×10 -34 Js). The notion of light quantization was first introduced by Planck. WebThe incident radiation has wavelength 300 nm, which is longer than the cut-off wavelength; therefore, photoelectrons are not observed. Significance If the photoelectrode were made …
