WebIn Einstein’s approach, a beam of monochromatic light of frequency f is made of photons. A photon is a particle of light. Each photon moves at the speed of light and carries an energy quantum E f. A photon’s energy depends only on its frequency f. Explicitly, the energy of a photon is E f = h f 6.13 where h is Planck’s constant. 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.

WebJan 30, 2024 · The photoelectric effect provided the first conclusive evidence that beams of light was made of quantized particles. The energy required to eject an electron from the surface of the metal is usually on the same order of magnitude as the ionization energy. ... The results from a photoelectric experiment are shown in Figure 2. \(\nu_0\) is the ... WebHertz experiment the electron beam may excite a mercury atom into the 3P 0 or 3P 2 state, but then it is stuck there (for a millisecond) and unable to absorb more energy. On the other hand, if the 3P 1 state is excited, it quickly de-excites (in 0.01 microseconds) and the atom is again available to absorb energy from the electron beam. The 1P 1 phi select
