Sunlight whose visible wavelengths range from 380 to 750 nm, is incident on a sodium surface. The work function for sodium is 2.28 ev. Find the maximum kinetic energy (in joules) of the photoelectrons emitted from the surface and the range of wavelengths that will cause photoelectrons to be emitted?
