(photons), each with energy hν to explain experimental data from thephotoelectric effect. This explained Max Planck's previous discovery of the Planck relation (E=hν) linking energy (E) and frequency (ν) as arising from quantization of energy. The factor h is known as thePlanck constant...
You will see that this quantum phenomenon finds an application in our everyday life, among others, in photoelectric sensors that detect and determine the intensity of the incident light (with the photoelectric effect equation, you can check if they will work at all in the sunlight). What is ...
Using the Rydberg Equation of the Bohr model of the hydrogen atom, for the transaction of an electron from energy level n = 7 to n = 3, find i) the change in energy. ii) the wavelength of the photon emitted. iii) The part...

In summary, the photoelectric effect experiment in question uses a light of frequency 8x1014Hz and a metal with a work function of 1.2eV. By using the equation Ek= hf-W, where h=6.63x10-34Js, f=8x1014Hz, and W=1.2eV, the maximum kinetic energy of the emitted electrons is calculated...
For photoelectric effect to take place, f>fo. Instantaneous emission of electrons explained: An electron is emitted if it gains enough energy from the photon. Since all photon energy is delivered immediately to the electron in a single collision, there is no time delay and is independent on th...

These phenomena can be explained in terms of radiation density calculated from Fresnel's equation and bulk optical properties of the semiconductor; no polarization dependence of the optical excitation need be invoked.doi:10.1016/0039-6028(74)90039-9M.S. Jazzar...
