Step-by-step solution

According to Einstein's photoelectric equation, the maximum kinetic energy ( E ) of emitted photoelectrons is given by: E = h - where h is Planck's constant, is the frequency of incident radiation, and is the work function of the metal. Comparing this equation with the equation of a straight line, y = mx + c , we get: y = E x = Slope, m = h (which is positive) y -intercept, c = - (which is negative) The x -intercept (where E = 0 ) is = h = ₀ , which is the threshold frequency. For frequencies ₀ , the kinetic energy
