Photon flux in a blackbody distribution
Webwhere e is the photon energy and Γ is the photon flux density. A plot of photon-flux density such as the one shown in Fig. 2.2(b) is useful in establishing the limits on the photocurrent from a solar cell. The expected maximum current can be calculated if the number of absorbed photons per unit area is multiplied by the charge per electron, q. WebEinstein was able to use Planck's quantization hypothesis to explain the photoelectric effect. As indicated in Figure 6.2.2 a minimum energy of 2.0 eV is required to eject a photon off of potassium, and so red light would not work, while green and purple would. Figure 6.2.2: Potassium requires 2.0eV to eject an electron, and a photon of red ...

WebPhoton number density Photons can exchange energy with each other through collisions only very weakly; in the presence of ions, the exchange may be much more rapid. As with the particles described in Lec. 13, the photons in a gas have a distribution of energies (and hence, of wavelengths), with few photons having little energy and few WebBlackbody Radiation • Ideal absorber and emitters of electromagnetic radiation – The hotter the body the more radiation emitted – The hotter the body the higher the energy of the …
