# Peak electric field in the wave

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

A point source emits light energy uniformly in all directions at an average rate Po with a a single frequency f. Show that the peak electric field in the wave is given by:
Eo = (µocPo/2 r2)
(Everything is under the square root)

I think we have to prove that the peak electric field is that equation but once again I am lost. Please show me a step by step step instructions on how to get this answer.

Solution:

The power that passes through a sphere of radius R is given by:

Power = S * (4πr2) --- (1)
Where,
S = the average value of the Poynting Vector
r = the ...
