Problem 1 - in a photoelectric effect experiment, radiation is incident upon a rubidium (RD) surface. Another metal surface is a parallel to this Rb surface such that the Rb and this metal surface form parallel plates. No electrons are ejected from the surface until the wavelength of the incident light falls below 571 nm. a) Find the work function of rubidium in units of eV. b) If the incident radiation has a wavelength of 350 nm, potential difference between the Rb surface and the other metal plate needed to bring the fastest photoelectrons to a halt. c) If the uncertainty in the speed of the electron in part(b) is 2.20*10* m/s, find the minimum uncertainty in a measurement of the electron's position. d) Consider a beam of photoelectrons made of electrons from part (b). These electrons are incident upon double-slit apparatus with a slit separation of 1.50x10m. The most likely place that the electrons would land on a viewing screen is directly across from the center of the double-slit apparatus. Find the angle from the normal to the apparatus that locates the next most likely place the electrons would land on the viewing screen.
