Wes -

Greg forgot to multiply by the number of atoms involved. Planck's constant
is atomic in nature and a fundamental constant in wave mechanics.

Tesla coils use oscillators which produce dampened waves. It appears from
this energy equation that the energy would increase as the frequency of the
waves increases, other factors being equal.
