Questions:
1. A metal with a work function of 4.5 eV is lit by incident light of frequency 3.5 x 1015 Hz. Predict the maximum
kinetic energy of the ejected electrons.
2. Refer to the graph to answer these questions
a.
b.
c.
d.
What is the value and name of the slope of the line?
What is the name and meaning of the x-intercept?
What is the name and meaning of the y-intercept?
Describe a procedure that could be used to collect
the data for this graph.
3. Show that the number of photoelectrons transferred from
the cathode to the anode per second (n) is equal to the photoelectric current (I) divided by the charge of an
electron (e). Hint: think about what the definition of current is.
4. The lowest light frequency that will eject electrons from silver is 1.14 x 1015 Hz. Find the work function of
silver.
