Photons of different frequencies are incident upon a copper surface, which has a work function 0=4.7 eV. Calculate the kinetic energy in eV and Joules of the ejected electron if the incident photon has a frequency v = 2x1015 Hz? What is the corresponding wavelength in meters of the photon? What is the corresponding velocity in meters per second of the electron? Repeat the calculations for an incident photon with a frequency v= 4x1014 Hz.
