10) A photoelectric effect experiment is done using light of some wavelength 2. The photoelectrons are observed to have a maximum kinetic energy of 7.0 eV. If the experiment is repeated using light of twice that wavelength (22 =221), on the same metal, it is found that the maximum electron kinetic energy is 2 eV. What is the work function of the metal?

In a photoelectric effect experiment you illuminate a metal with light of an unknown wavelength and measure the maximum kinetic energy of the photoelectrons to be .75 eV. Then you illuminate the same metal with light of a wavelength known to be 2/3 of the first wavelength and measure a maximum kinetic energy of 2.4 eV for the photoelectrons. a) Find the first wavelength, in nanometers. b) Find the metal's work function, in electron volts.
