Photoelectric Effect Summary – The Physics Hypertextbook
20/07/2010 · Best Answer: The idea of work functions refer to the photoelectric effect -- you shine light on a metal, and if the frequency is high enough, an electron gets kicked off.... Work Function : The work function of a metal is the energy corresponding to the threshold frequency of the metal. The work function is usually denoted by the Greek letter φ.The maximum kinetic energy of the ejected electrons depended on the frequency of the incident photon and the work function.

Photoelectric Effect Questions
Emission mechanism. The photons of a light beam have a characteristic energy proportional to the frequency of the light. In the photoemission process, if an electron within some material absorbs the energy of one photon and acquires more energy than the work function (the electron binding energy) of the material, it is ejected. how to tell if a usps tracking number is fake energy of the photon must be equal to or greater than the work function. If the photon’s energy, E, is just enough to release a photoelectron, then its frequency is called the threshold frequency, f. How to stop rabbits chewing their hutch

  • The work function of the silver surface is 4.7 eV. b) Calculate the energy, in eV, of a single photon of light of wavelength 254 nm (2.54 x 10-7 m). c) What is the kinetic energy, in eV, of the fastest moving photoelectrons ejected by light of 254 nm?
  • 12/01/2010 · Best Answer: one is an energy and one is a frequency work function is the energy required to take an electron 'out of' (ionise it) the atom the threshold frequency is the frequency of light that has the same energy (hf) as the work function if light hitting atom has frequency (and therefore energy) greater
