Problem: In his explanation of the threshold frequency in the photoelectric effect, Einstein reasoned that the absorbed photon must have a minimum energy to dislodge an electron from the metal surface. This energy is called the work function (ϕ) of the metal. What is the longest wavelength of radiation (in nm) that could cause the photoelectric effect in calcium, ϕ = 4.60 x 10−19 J?
