1. The problem statement, all variables and given/known data How much energy is transported across a 1.15 cm^2 area per hour by an EM wave whose E field has an rms strength of 36.5 mV/m? 2. Relevant equations E=hv? The big problem I'm having is that I don't know what formulae to use. 3. The attempt at a solution I know what V/m = J/C = J/(A*s) and I know I need to get to J/h. But I don't know what I have that would include Amps or Coloumbs to get rid of that part (I've resorted to trying to sort out units in the face of the lack of equations. Thanks!
