A light source of wavelength λ illuminates a metal and ejects photoelectrons with a maximum kinetic energy of?
A light source of wavelength λ illuminates a metal and ejects photoelectrons with a maximum kinetic energy of 1.00 eV. A second light source of wavelength 1/2(λ) ejects photoelectrons with a maximum kinetic energy of 4.30 eV. What is the work function of the metal?
