Photoelectric effect

Assignment

  1. Determine the minimum frequency required to observe the Photoelectric Effect for an EM radiation incident on a zinc metal surface.
  2. Determine the target material if the threshold frequency of EM radiation is 5.5 × 1015 Hz in a particular photoelectric experimental setup.
  3. Determine the maximum kinetic energy of photoelectrons emitted from a zinc metal surface, if the incident frequency is 3 × 1015 Hz.
  4. What should be the stopping potential for photoelectrons if the target material is platinum and the incident frequency is 2 × 1015 Hz?
  5. What should be the minimum applied potential for complete stoppage of photocurrent in an experiment if the target material is copper and the incident frequency is 2.7 × 1015 Hz?
