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:- WebJan 20, 2012 · 1.For a given metal and frequency of incident radiation, the rate at which photoelectrons are ejected is directly proportional to the intensity of the incident light. 2.For a given metal, there exists a certain minimum frequency of incident radiation below which no photoelectrons can be emitted. This frequency is called the threshold frequency. list of fed interest rate changes

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. WebApr 13, 2024 · From the real part, Zʹ versus frequency plots, at different illumination conditions such as, under dark condition, illumination of white light and red laser light with variable intensities such as 6.4 µW/cm 2, 24.04 µW/cm 2, 58.67 µW/cm 2, 5436.61 µW/cm 2 (Fig. 7), it is very prominent that Zʹ is maximum in the low-frequency range and ... WebA graph is drawn between light intensity along x-axis and the photocurrent along y-axis. From the graph in Figure 7.9, it is evident that photocurrent – the number of electrons emitted per second – is directly proportional to the intensity of the incident light. Here, intensity of light means brightness. imagine hair and skin

WebJul 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 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. This means that the photons with

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.
