hc 3. Photoelectric Effect. Kemut = hf - W he - Wr a) The work function for Tungsten is 4.58 eV. What is the longest wavelength light that will cause the photoelectric effect to occur in Tungsten? b) Calculate the maximum kinetic energy of electrons emitted from Tungsten when the wavelength of incident light equals 200.0 nm. c) The longest wavelength of light that will cause emission of electrons from silver is 262 nm. What is the work function for silver? d) What is the maximum kinetic energy of electrons emitted from a silver surface when the incident light has wavelength 150.0 nm? e) A TV remote emits infrared light with a wavelength of 1873 nm. The receiver won't cause anything to happen unless electrons are emitted. What is the largest work function the receiver can have so that the remote will work?
