A sinusoidal electromagnetic wave from a radio station passes perpendicularly through an open window that has area of .5m^2. At the window, the electic field of the wave has rms value of .02 V/m. How much energy does this wave carry through the window during a 30sec commercial?
power value is 3.9*10^26 and there is no efficiency of the sail. i tried your way and i got answer to be .04 m^2 but actual answer is 6.48 km^2. I got that answer by guessing...
Thanks anyways.
whats up guys. help me out
