WebAug 19, 2024 · in this video we're gonna change the brightness and the color of the light or the intensity and the frequency of the light and see how that affects the graph of the photoelectric effect and the … Webequations. Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy ( Kmax) of the photoelectrons to the frequency of the absorbed photons ( f) and the threshold frequency ( f0) of the photoemissive surface. Kmax = h ( f − f0)

WebThe most important current range is for voltages on the current meter between 1 to 10mV. This may change depending on the light intensity you are using. To determine this range take a quick set of data for one filter and plot I (in mV) versus V R. The curve will have a knee in it above which the current increases rapidly (see Fig. 4).
WebMay 9, 2024 · If you keep intensity fixed , and change the frequency then the Saturation current will in fact decrease. This is because Intensity = nhf/A ; for intensity to remain constant with increasing frequency the number of photons striking the metal surface must decrease. The graph you are referring to has different frequency but same current , which ... highlight div on clickhighlight directive angularWebJul 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 … highlight div cssWebThe different types of graphs are: Photoelectric current vs Retarding Potential; Saturated Current vs Intensity; Vmax V/sV; Potential vs Current; Stopping potential vs Frequency; … highlight diversityWebEX-5549A Photoelectric Effect Page 1 of 7 .
