Photocurrent vs frequency graph
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 … 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 …

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:- WebNov 28, 2024 · The graph shows the variation of photocurrent for a photosensitive metal (a) What does X and A on the horizontal axis represent? (b) Draw this graph for three different values of frequencies of incident radiation v 1, v 2 and v 3 (v 3 > v 2 > v 1) for the same intensity. (c) Draw this graph for three different values of intensities of incident radiation I …
WebJun 21, 2003 · If you look at a graph of photocurrent (emitted obviously during the photoelectric effect) VS stopping/retarding voltage, you'll find that the photocurrent (under the constant light frequency) is constant upto a critical stopping voltage where it just falls to zero. (you may find this graph in Jacaranda). Now I don't get how this is possible. 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 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. 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
Webresponse, which is the frequency at which the photodiode output decreases by 3dB. It is roughly approximated by: ( 3 ) There are three factors defining the response time of a photodiode: 1. t ... to light, and it is defined as the ratio of the photocurrent I P to the incident light power P at a given wavelength: ( 5 ) In other words, it is a ...
