Photons and the Photoelectric Effect:
Energy of a photon:
Planks constant:
E = hf
E = hc
hc = 1240eV nm
h = 6.626 1034 J s
h = 4.136 1015 eV s
Photoelectric Effect: hf = KEmax + W0
W0 = hf 0

Momentum of a Photon
Simple Harmonic Motion
Hookes law: F = kx ([k] = N/m)
the sign indicates that the direction of the force is opposite the displacement
