WebAll photoelectric effect graphs: Effect of intensity/frequency. Effect of intensity and frequency. Stopping potential vs frequency graph. Stopping potential v/s frequency ... Stopping potential is the minimum negative voltage applied to the anode to stop the photocurrent. The maximum kinetic energy of the electrons equal the stopping voltage ... 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 ...
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. WebEspecially, in reverse bias region, photocurrent (Iph) increases with increasing illumination intensity (P) due to the formation of electron–hole pairs. The double-logarithmic Iph-P …
