Photoelectric Effect, Work Function, Threshold Frequency, Wavelength, Speed & Kinetic Energy, Electr

This chemistry video tutorial explains how the photoelectric effect works. It also explains how to use the work function of metals to calculate the threshold frequency and maximum wavelength of light necessary to eject an electron off the surface of an active metal. In addition, it explains how to calculate the speed of an electron as well as the kinetic energy of an electron in electron volts. You need to know how to convert electron volts to joules and vice versa. This video provides all of the formulas and equations needed including plenty of practice problems and examples.
