WebbPHYS 263 – LAB 10 DILLES Lab 10 – The Photoelectric Effect 11 November 2011 Jacob Dilles G00513892 Abstract We experimentally derive Planck's Constant, denoted , by measuring photocurrent while varyingℏ reverse voltage applied to a phototube illuminated by several Light Emitting Diodes. By simple WebbThe photoelectric effect is the process of a photon being absorbed by an atom ejecting an electron. This process of interaction usually occurs between photons and electrons of inner shells. Consequently, more loosely bound outer shell electrons can fill the inner shell leading to the emission of x-rays.
