Homework Statement
The wavelength associated with the cut-off frequency, for silver is 325 nm.
a) What is the work function for silver?
b) Find the maximum kinetic energy and speed of the electrons ejected from a silver surface by ultraviolet light of wavelength 254nm
Homework Equations
f= c/325nm
The Attempt at a Solution
f = c/3.25 * 10 ^ -7 = 9.23 * 10 ^ 14
9.23 * 10 ^14 = hc/325e - work function
