Photoelectric effect: When certain metals are exposed to a beam of light, the electrons are ejected from the metal. This phenomenon is called photoelectric effect. The electrons ejected are called photoelectrons. The results of this experiment were: 1. The electrons are ejected from the metal surface only as the beam of light strikes the

In this lab you will determine the magnitude of Planck's constant, h, employing the photoelectric effect experiment and associated mathematical framework. The overall purpose of the activity is to demonstrate the particle nature of light. electron V A Collector Emitter Light Figure 1: Schematic of the photoelectric effect apparatus. Theory:

The photoelectric effect happens when particles of light, called photons, hit a metal. Electrons hanging on to the outside of the metal can get knocked off if the photons hit them hard enough (that is, with enough energy). The photoelectric effect At the turn of the century, physicists who experimented with electricity had noticed something about the interaction of light, metals, and electric current. The Photoelectric Effect This topic is so important, it deserves its own note set. In 1887, Heinrich Hertz discovered that certain metals emit electrons when light is incident on them. This was the first instance of light interacting with matter, so it was very mysterious. In 1905 Albert Einstein, a 3rd Class

The photoelectric effect was discovered by Heinrich Hertz in 1897 while performing experiments that led to the discovery of electromagnetic waves. Since this was just about the time that the electron itself was first identified the phenomenon was not really understood.
