In a photoelectric experiment a parallel beam
WebThis experiment requires the use of several different monochromatic light beams, which can be obtained from the spectral lines that make up the radiation produced by excited … Webequations. Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy ( Kmax) of the photoelectrons to the frequency of the absorbed photons ( f) and the threshold frequency ( f0) of the photoemissive surface. Kmax = h ( f − f0)

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. WebIn a photoelectric experimental arrangement, light of frequency f is incident on a metal target whose work function is ϕ = hf/3 as shown, In column I, KE of photoelectron is mentioned at various locations/instants and in column II, the corresponding values.
