Solved: Photons of energy 6.0 eV are incident on a metal.
Chapter 8, Problem 81GP(choose chapter or problem)
Photons of energy 6.0 eV are incident on a metal. It is found that current flows from the metal until a stopping potential of 4.0 V is applied. If the wavelength of the incident photons is doubled, what is the maximum kinetic energy of the ejected electrons? What would happen if the wavelength of the incident photons was tripled?
