Photoelectric effect: negative collector. All photoelectric effect graphs: Effect of intensity/frequency. Effect of intensity and frequency. WebThe 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.
