Question

Work function of potassium is 2.2 eV. What is the threshold frequency of photoelectron?

Answer 1

Answer:

Cut-off frequency depends only on the work function of the metal and is in.Solution The threshold wavelength for observing the photoelectric effect in silver is ... a photoelectron from potassium, given the work function of potassium 2.24 eV
