the power density of sunlight, at the earth, is roughly 1 kilowatt/meter^2. How large is the rms magnetic field strength?
Homework Equations
The Attempt at a Solution
I tried using the equation for power density S = E(rms)^2=√(εμ), then substituting B(rms)/c for E(rms), and subsequently solving for B(rms). However this does not give me the correct solution and I am now confused
