Photocurrent vs frequency graph
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 … WebFor a fixed value of frequency and the potential between the metal plate and collector, the photoelectric current is noted in accordance with the intensity of incident radiation. It shows that photoelectric current and intensity of incident radiation both …

WebEasy Solution Verified by Toppr Correct option is A) The intensity of incident photons (i) and the photoelectric current (I) is directly proportional. As the intensity of incident light increases the photoelectric current produced also increases. So the correct answer is option (A.) Solve any question of Dual Nature of Radiation And Matter with:-
WebThe main graph shows the excitation density dependence (at constant excitation volume) of the final photocurrent amplitude (dashed curve) and of the build-up rate as given by the inverse of Eq. 12.16 for q = 0.1 to q = 0.9 in steps of 0.2. The slope of the middle build-up rate curve on the log-log plot is 0.5. 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
WebSep 12, 2024 · According to the classical description, the kinetic energy of photoelectrons should not depend on the frequency of incident radiation at all, and there should be no cut … WebApr 12, 2024 · Graph connecting 'KE max ' and frequency: Maximum kinetic energy of photoelectrons versus frequency of incident radiation graph . Now, if we increase the reverse potential, the photocurrent gradually decreases and becomes zero at a particular reverse potential. This minimum applied reverse potential is called stopping potential V 0. …
