Question

When light of wavelength 350 nm is incident on a metalsurface, the stopping potential of the photoelectrons is 0.500 eV.
Part A
What is the threshold frequency?
Part B
What is the maximum kinetic energy of the electron (ineV)?

Part C

What is the work function of the metal (in eV) When light of wavelength 350 nm is incident on a metalsurface, the stopping potential of the photoelectrons is 0.500 eV.
Part A
What is the threshold frequency?
Part B
