Question
Photons of energy 12eV are incident on a metal. It is found that current flows from the metal until a stopping potential of 8.0V is applied.
What would happen if the wavelength of the incident photons was tripled?
Would the energy be 4eV,so 12/3=4, and there will be no current flow? Is this correct? Please help!Thank you.
