The work function for the platinum is 6.35 eV.
(i) Transform the value of the work function from electron volts to joules.
(ii) Determine the cutoff frequency for the platinum.
(iii) Find at what maximum wavelength, light incident on platinum releases photoelectrons from the surface of platinum?
(iv) When light of energy 8.3 eV is incident on the platinum, then find out the maximum kinetic energy of the ejected photoelectrons? Provide the answer in electron volts.
(v) For photons of energy around 8.3 eV, then what stopping potential would be needed to arrest the current of the photoelectrons?
