Physics Questions & Solutions Question 27. The work functions of Caesium (Cs), Potassium (K) and Sodium (Na) are 2.14 eV, 2.30 eV and 2.75 eV respectively. If incident electromagnetic radiation has an incident energy of 2.20 eV, which of these photosensitive surfaces may emit photoelectrons? (1) Cs only (2) Both Na and K (3) K only (4) Na only Answer. (1) Cs only Solution. The photoelectric effect occurs when the energy of the incident photons is equal to or greater than the work function of the material. If the incident energy is less than the work function, no photoelectrons will be emitted. In this case, the incident energy is 2.20 eV. Comparing this to the work functions: - The work function of caesium (Cs) is 2.14 eV. Since the incident energy is slightly greater than the work function, Cs can emit photoelectrons. - The work function of potassium (K) is 2.30 eV. The incident energy is slightly less than the work function, so K may not emit photoelec
