Homework Statement
If electrons can be ejected from a silver surface using light with wavelengths as large as 262 nm. What is the work function for silver?
Homework Equations
work function=hf
c=f[tex]\lambda[/tex]
The Attempt at a Solution
Given the wavelength, I solved for f = (3x108)/(262x10-9) = 1.15x1015
Then times by Planck's constant to get work function=(6.63x10-34)x(1.15x1015) gives me 7.60x10-19
...which is completely silly because the answer is supposed to be near 4.74
