A certain metal in the photoelectric effect experiment has a work function of 2.3 eV. For a given experiment, the maximum kinetic energy of the ejected electrons is 1.6 eV.
What is the wavelength of the incident photons?
What is the DeBroglie wavelength of the ejected electrons?
What is the maximum wavelength of photons that would eject electrons from this metal?
If the intensity of light was increased, how would the above answer change?
