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
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.
WebMar 18, 2024 · Current is not dependent on the frequency of photons. Frequency of photons is only related to the kinetic energy. Thus the current remains the same. Hence, option B is …
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. is double your money a good investmentWebJul 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 is doubletwist safeWebeVo = mv2max The above equation indicates that the stopping potential depends upon the velocity of the fastest electron. The experiment is repeated with the incident radiation of same frequency, but of higher intensities I2 and I3. It is found from the graph, the saturation currents are proportional to the intensities of the radiation. ryan carthyWebFor 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.
