Photoelectric Effect

The photoelectric effect is the emission of electrons from the surface of a metal when electromagnetic radiation (such as visible or ultraviolet light) shines on the metal. In this lab, you will study the effect varying the light intensity and frequency has on the energy of the emitted electrons and the magnitude of the photo-current. You will also determine Planck's constant.
