Electric Field of an EM wave

[skibum143]

Homework Statement

A 1.10m long FM antenna is oriented parallel to the electric field of an EM wave. How large must the electric field be to produce a 1.28 mV voltage between the ends of the antenna?

Homework Equations

u = EoErms^2
I = uc
Intensity = Power / area

The Attempt at a Solution

I found u to be 1.45E-17 using E0 and Erms of .00128V
Then I found I to be 4.35E-9
Then I found P to be 1.65E-8

I'm not sure I'm using the right equations to find the electric field, I don't really know what variable represents it?

How about using the equation V=E*d?

yep, that's a lot easier. oops. thanks!
