An experiment is performed where light of different frequencies is shined on a silver plate. The work function for silver is 4.73 eV. (a) What is the lowest frequency (the "cutoff" frequency, in Hz) of light incident on sodium, below which no photoelectrons will be emitted from its surface?(b)What is the longest wavelength (the "cutoff" wavelength, in nm) of light incident on sodium, above which no photoelectrons will be emitted from its surface?(c) Photons of energy 3.62 eV are incident on the sodium plate. What is the maximum kinetic energy (in eV) of the ejected photoelectrons?
