Answer: In an experiment to study the photoelectric
Chapter , Problem 88AE(choose chapter or problem)
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 \(" v_{0} " \) corresponds to light with a wavelength of
\(542 \mathrm{~nm}\).
(a) What is the value of \(v_{0} \text { in } \mathrm{s}^{-1}\)
(b) What is the value of the work function of the metal in units of \(\mathrm{~kJ} / \mathrm{mol}\) of ejected electrons?
(c) Note that when the frequency of the light is greater than n0, the plot shows a straight line with a nonzero slope. What is the slope of this line segment?
