Question
In an experiment to study the
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 “n0” corresponds to light
with a wavelength of 542 nm. (a) What is the value of n0 in s - 1?
(b) What is the value of the work function of the metal in units
of kJ>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?
