In 1839, Alexandre Edmond Becquerel discovered the photovoltaic effect while studying the effect of light on electrolytic cells. Though not equivalent to the photoelectric effect, his work on photovoltaics was instrumental in showing a strong relationship between light and electronic properties of materials. In 1873, Willoughby Smith discovered photoconductivity in selenium while testing the met… WebThe Wave equation. c = λ ν. where, the wavelength is, λ, in meters, the frequency of the photon is, ν, in Hertz (Hz), and the speed of light is c = 3.00 X 108 m/s. This means that the frequency and wavelength are inversely proportional to each other. So how do we relate this to the photoelectric effect equation?
