Classical electromagnetism predicted that v0 should have increased as the intensity of the incident light increased. on the contrary, it was found that v0 increased as the frequency f of the light increased. the voltage v0 was found to obey the following linear relationship: v0=mf? b v_{0} = mf - b ,where m m and b b are numerical constants (representing the slope and the intercept, respectively). by comparing this equation to your answer from part b, find an expression for the intercept b b. (notice that mf mf in this equation changes with different light but b b is a constant of the metal.)express your answer in terms of ? phi and e e.
