A photon at 300 nm will kick out an electron with an amount of kinetic energy, KE300. If the wavelength is halved and it hits an electron in the metal with the same energy as the previous electron, what is the energy of the electron coming out?
a. Less than 1/2 KE300
b. 1/2 KE300
c. = KE300
d. 2 * KE300
e. More than 2 * KE300
