a the work functions of au and cu are 53 and 47 ev what is the ma41129
a) The work functions of Au and Cu are 5.3 and 4.7 eV. What is the maximum wavelength of light that will cause photoemission of electrons from Au? If this light shines on Cu, what is the kinetic energy of b) Solve Schrodinger's equation to write the wave function of an electron emitted from Cu in part a. Assume the electrons are far from the sample and emitted with velocities along the positive x-axis. Include the numerical values of the variables specific to this problem. c) Apply p, to this emitted electron to calculate its momentum. Show that this momentum is consistent with the total energy of the emitted electron. d) Sketch (x) and (k) for this emitted electron and use the sketch to discuss the uncertainty in x and p.
