WebAccording to Einstein's photoelectric equation, the plot of the kinetic energy of the emitted photoelectrons from a metal Vs the frequency, of the incident radiation gives a straight … WebStep 3: Analyze the graph. Now, if we change the intensity of incident radiation, then h, c, e and ϕ 0 will not change. Therefore, neither the slope of the graph nor the y-intercept cut by the graph will change on changing the intensity of incident radiation. So, the graph will not change. Hence, option (d) is correct.
