Photocurrent vs intensity graph
WebPhotocurrent linearity is determined by measuring the small change in photocurrent as a result of a small change in the incident light power as a function of total photocurrent or incident light power. Non-Linearity is the variation of the ratio of the change in photocurrent to the same change in light power, i.e. ∆I/∆P. WebApr 13, 2024 · In the I–V graph, slight non-linearity has been found under dark condition and also found to increase with the increase in incident light intensity. According to Fig. 5, the photocurrent was found to increase with the incident light intensity and obtained the maximum under 5.436 mW/cm 2 red laser light.

WebFeb 11, 2024 · I was puzzled by the behavior of the simulation until I read the PhET Tips for Teachers of the Photoelectric Effect (same page as the software on Phet site):. In the default setting, since the intensity of light is proportional to the number of photons times the frequency, if you increase the frequency while holding the intensity constant, the number … 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. A bright light has more intensity ...
