When light of frequency equal to 2.11 X 10 s shines on the surface of gold metal, the kinetic energy of ejected electrons is found to be 5.83 X 10" J. What is the work function of gold ... 

Figure 1.10 A plot of the kinetic energy of ejected electrons versus the frequency of incident radiation.

Ek-El,. This energy is then used up in ejecting an Auger electron from the Lu orbital, any excess energy being converted into kinetic energy of the electron. 

Internal Conversion. As an alternative to the emission of a y-ray, the available energy of the excited nuclear state can be transferred to an atomic electron and this electron can then be ejected from the atom. The kinetic energy of this electron is where E is the energy by which the... 

The kinetic energy of the electron ejected from the metal increases linearly with the frequency of the incident radiation according to Eq. 5. 

Consider the following statements about electromagnetic radiation and determine whether they are true or false. If they are false, state why they are false, (a) Photons of ultraviolet radiation have less energy than photons of infrared radiation, (b) The kinetic energy of an electron ejected from a metal surface when the metal is irradiated with ultraviolet radiation is independent of the frequency of the... 

Because the kinetic energies of photoelectrons depend on the photon energy, equ. (1.29a), but the kinetic energies of Auger electrons are independent of the photon energy, equ. (1.29b), the processes can be easily distinguished in an experimental spectrum of ejected electrons if the kinetic energies are observed at... 

When a photon of wavelength X = 400 nm strikes a Cs target, an electron is ejected. Calculate the kinetic energy of the electron if the maximum wavelength to obtain a photoelectron from Cs is 660 nm. 

Using the law of conservation of energy, relate the work function of a metal to the wavelength of light used to eject electrons in the photoelectric effect and the kinetic energy of those electrons (Section 4.4, Problems 25-28).
