WebJul 6, 2024 · Homework Statement. In photoelectric effect I-V graphs, for the same intensity but with different light frequencies (f2>f1), the I-V graph has the same max photocurrent but Vs2 > Vs1 . 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 ... 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 …
WebApr 6, 2024 · The following graph shows photoelectric current vs intensity of incident radiation. Note: Above the threshold frequency of a photosensitive material, the stopping potential or equivalently the maximum kinetic energy of the photoelectrons is directly proportional to the frequency of the incident radiation, but is independent of its intensity. Webis determined by measuring the electric current; is directly proportional to the intensity of the incident light when frequency is constant; On a graph of maximum kinetic energy vs. frequency… all curves are linear with slope equal to Planck's constant. h = 6.63 × 10 −34 J s.
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 ...
WebIn the early 1900 s it was found that the inetic energy of the eloctrons emitted in the photoelectric effect was dependent on the wavelength, or frequency, and independent of intensity, while the magnitude of the photoelectric current was dependent on the intensity as predicted by the quantum model. shanthi electricals nungambakkamWebThe effect of changing incident frequency v can also be studied from the plot of photoelectric current Vs potential applied across CD, keeping the intensity of incident radiation same. From graph, we see that i max is same in all cases (for same intensity).
