Photocurrent vs frequency graph
WebThe photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics. WebStopping potential vs frequency graph. Stopping potential v/s frequency. Comparing stopping potential, and max. speed: Solved example.

Theoretically, at the stopping voltage, we expect the current to be zero. However, as
WebJul 6, 2024 · If we concentrate between the cutoff and the saturation regions of the I-V graph, we can see that at any given applied voltage, the photocurrent from the case with light freq f2 is higher than that with f1. Seems the saying increase freq only increases max KE but not the photocurrent cannot explain this observation. Homework Equations WebThis minimum frequency is also called the threshold frequency, and the value of ν 0 \nu_0 ν 0 \nu, start subscript, 0, end subscript depends on the metal. For frequencies greater than ν 0 \nu_0 ν 0 \nu, start subscript, 0, end subscript, electrons would be ejected from …
WebCurrent is flow of electrons in a given time i.e if the intensity of the light is Constant then Photons incident on Cathode (ejector plate) is also constant. As we know that minimum K.E, that photo-electron can have is 0 and max. is energy of … WebThe figure shows a plot of photocurrent v/s anode potential for a photo sensitive surface for three different radiations. Which one of the following is a correct statement? A curves (b) and (c) represent incident radiations of same frequency having same intensity B
WebAs the frequency goes from zero to higher values, the electron is lifted higher out of the hole, until finally at its threshold frequency it’s out. When there are no photons hitting it (frequency = 0 Hz), it is completely attached to the material. This is why they appear as negative values on the graph. Planck’s Constant
