Explain the nature of the curves on the basis of Einstein's equation. (c) Solution WebeVo = 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.
