WebWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission , and the electrons that are ejected from the metal are called … WebJul 29, 2024 · The question in the original post was a good one. Usually the response curves of the photodiodes, e.g. silicon photodiodes are given as a graph of response R vs. wavelength, and the response does increase nearly linearly with wavelength until the photodiode reaches the long wavelength cut-off where the photon energy is insufficient to …
WebPhysics questions and answers. 4) In the photoelectric effect experiment, the graph of current versus battery voltage for a metal with light of a particular frequency and intensity shining on it looks like the curve below. This graph represents current vs voltage for 200nm light shining onto Cadmium (Cd) which has a work function of4.07 eV. WebThe graph between the photoelectric current and the intensity of light is a straight line when the frequency of light used is above a specific minimum threshold value. ... The saturation current depends on the intensity for a known value of frequency. At the same time, we see that the stopping potential does not depend on the intensity over a ...
