AP Physics 2
15.5 The Photoelectric Effect
Monochromatic ultraviolet light with photon energy \(8.23 \times 10^{-19} \text{ J}\) shines on a clean sodium plate inside an evacuated chamber. The work function of sodium is \(3.68 \times 10^{-19} \text{ J}\), and the mass of an electron is \(9.1 \times 10^{-31} \text{ kg}\). What is the maximum speed of the photoelectrons ejected from the sodium plate?
