Unformatted text preview: the gas. (2 pts) b. Determine the energies of photons in the emission spectrum of these atoms. (2 pts) 27. Light of a single wavelength shines on a metal which has a work function of 3.0 eV. Photoelectrons with kinetic energy of up to 5.0 eV are emitted. a. What energy or range of energies do the incident photons have? (3 pts) b. If the intensity of the incident light increases, does the maximum kinetic energy of photoelectrons go up, go down, or stay the same? Explain. (2 pts) c. If instead the wavelength of the light increases, does the maximum kinetic energy of photoelectrons go up, go down, or stay the same? Explain. (2 pts)...
