In an experiment to study the photoelectric effect, a scientist measures the kinetic energy of ejected electrons as a function of the frequency of radiation hitting a metal surface. She obtains the following plot. The point labeled “ v₀ ” corresponds to light with a wavelength of 680 nm. (a)What is the value of in s^-1? (b)What is the value of the work function of the metal in units of of kj/mol ejected electrons? (c) What happens when the metal is irradiated with light of frequency less than V_o? (d) Note that when the frequency of the light is greater than V_o, the plot shows a straight line with a nonzero slope. Why is this the case? (e) Can you determine the slope of the line segment discussed in part (d)? Explain.
