Includes one easy to follow worked example for the photoelectric effect showing how to determine the minimum frequency and wavelength of light needed to emit an electron from a metal with a know work function. You can see a listing of all my videos at my website, stepbystepscience.com
The photoelectric effect is the emission of electrons when light is shined on a material. Electrons emitted in this way can be called photoelectrons.
In 1905, Albert Einstein published a paper advancing the hypothesis that light energy is carried in discrete quantized packets to explain experimental data from the photoelectric effect. This was a key step in the development of quantum mechanics. In 1914, Millikan's experiment supported Einstein's model of the photoelectric effect. Einstein was awarded the Nobel Prize in 1921 for his discovery of the law of the photoelectric effect.
