If the threshold wavelength in the photoelectric effect increases when the emitting metal is changed to a different metal, what can you say about the work functions of the two metals?
Solution 5Q: We have to correlate the work function of two different metal in terms of their threshold wavelength. Step 1 of 2 Concept: Kinetic energy(KE) of an emitted electron when a light of wavelength ()falls on a metal whose threshold wavelength is ( ) is given as, o 1 1 KE = hc ( o) …(a) Work function of the metal is defined as the minimum amount of energy just enough to remove the electron from its atom. Mathematically, hc W = o …(b)
