(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A radio station is allowed to broadcast at an average power not to exceed 24 kW.

If an electric field amplitude of 2.6×10−2 V/m is considered to be acceptable for receiving the radio transmission, estimate how many kilometers away you might be able to hear this station.

2. Relevant equations

P/A = e_0*c*E^2

3. The attempt at a solution

e_0*c*E^2/P = 1/pi r^2

sqrt(24000/(8.85 *10^-12*3*10^8*pi)) = 65.2 km
