Photocurrent vs frequency graph

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. http://www.studyphysics.ca/2007/30/07_emr/34_photo_graphs.pdf

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 WebApr 12, 2024 · The frequency of the photon is directly proportional to its energy; high-frequency photons have greater energy than the low-frequency photons.

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 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.
