When a particular metal is illuminated with photons, one electron is observed for each absorbed photon. What effect would INCREASING the wavelength and number of photons have on the electrons leaving the surface?Select one:a. There would be more electrons leaving the surface. b. They would have higher kinetic energy. c. The electron velocity would be lower. d. The kinetic energy of the electrons would be the same for each electron ejected, but less electrons would be ejected. e. Two photons might be required to eject the electrons.
