Question:
In the photoelectric effect, the energy of the absorbed photon is equal to the sum of the energy for the threshold frequency 
of the metal and the kinetic energy of the ejected electron. When light with a wavelength of 400 nm strikes potassium metal, the ejected electrons have a kinetic energy of 1.38 × 10-19 J. What is the photoelectric threshold frequency (in s-1) for potassium?
