The Photoelectric Effect (with illustrations)

[Ostronomos]

[b]While Planck was dramatically breaking light up into quanta, another Physicist discovered something about the Photoelectric Effect.[/b]

This phenomenon was first observed in the 1880's, when it was discovered that light shone on certain metals blast out electrons. Early research used high-frequency ultraviolet light and established that the more intense the light beam was, the larger the electricity produced. It is important to note that the frequency of the light produces an effect, not the color. According to the "Quantum Physics Bible".

In summary, the photoelectric effect is the emission of electron from a material caused by electromagnetic radiation. According to Wikipedia.
