- A light source of wavelength λ illuminates a metal and ejects photo electrons with a maximum kinetic energy of 0.67 eV. A second light source with half the wavelength of the first ejects photoelectrons with a maximum kinetic energy of 3.3 eV. What is the work function of the metal? Answer in units of eV.In a photoelectric effect experiment you illuminate a metal with light of wavelength 290 nm and measure a stopping potential of 1.2 V. What is the work function of the metal, in electron volts?The wavelength of a red spectral emission line is 670.0 nm. At what kinetic energy (in J) would an electron have that wavelength as its de Broglie wavelength?
