3. UV radiation photons with a wavelength of 3.45 x 10-7 m are incident on a metal surface in a vacuum. Photoelectric effect took place and electrons were instantaneously emitted from the surface with a maximum kinetic energy of 1.52 ev (electron-volt is another unit for energy, where 1 eV = 1.602 x 10-9). What is the Work Function, o of the unknown metal?
