Physics conceptional question Please help
THANK YOU DAMON!

Physics conceptional question Please help
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...

Physics PLEASE HELP
When UV light of wavelength 295nm falls on a metal surface, the maximum kinetic energy of emitted electrons is 1.50eV. What is the work function of the metal? W0 in eV

Physics Please help out
