The maximum wavelength of incident light that releases
photoelectrons from the surface of a platinum sample is 195 nm.
Calculate:
The cutoff frequency for platinum:
The work function for platinum in eV
The minimum energy required to release photoelectrons from the
platinum surface:
The maximum kinetic energy of the ejected photoelectrons, in eV,
if the incident photons’ wavelength is 124 nm:
The stopping potential required to reduce the photocurrent to
zero:
