Millikan experiment photoelectric effect
WebLesson 33: Photoelectric Effect Hertz Experiment Heinrich Hertz was doing experiments in 1887 to test some of Maxwell's theories of EMR. One of the experiments involved using a coil of wire as a receiver to detect EMR produced by a separate device. This was very much like Maxwell's own experiments with low frequency AC radiation. WebIn Millikan's photoelectric apparatus, monochromatic light was incident on each of the newly-cleaned metal plates in turn. The resulting photoelectrons were collected by …
