Question

I was able to calculate Intensity of the radio waves which is 1*10^-5 W/m^2 and Bmax which was 2.9*10^-10 T. Now I need to find the total power output of the ISS radio transmitter and Im really not sure how I relate these two or what equation I need to use. I also need to know what assumptions may be made about the calculation.  I was thinking one could be the velocity of the wave is the speed of light, but Im not sure if thats right or what the other possibilities are. Can I get someone to explain this to me please? You are a NASA mission specialist on your first flight aboard the space shuttle. Thanks to your extensive training in physics, you have been assigned to evaluate the performance of a new radio transmitter on board the International Space Station (ISS). Perched on the shuttle's moveable arm, you aim a sensitive detector at the ISS, which is a distance of 3.0km away. You find that the electric-field amplitude of the radio waves coming from the ISS transmitter is 8.7 times 10?2 V/m and that the frequency of the waves is 214MHz I was able to calculate Intensity of the radio waves which is 1*10^-5 W/m^2 and Bmax which was 2.9*10^-10 T.

Explanation / Answer

intensity I = power/area = Emax^2/2 uoC

power = 8.7*10^-2)^2* 3.14* 3000*3000 = 4.27 *10^5 watts
