• The photoelectric effect is a phenomenon that occurs when light shined onto a metal surface causes the ejection of electrons from that metal.
  • If the frequency of the incident light is too low (red light, for example), then no electrons are ejected even if the intensity of the light is very high or it is shone onto the surface for a long time.
  • If the frequency of the light is higher (green light, for example), then electrons
