An 800 kHz radio signal is detected at a point 9.5 km distant from the transmitter tower. The electric field amplitude of the signal at that point is 230 mV/m. Assume that the signal power is radiated uniformly in all directions and that radio waves incident upon the ground are completely absorbed. Find the average electromagnetic energy density at that point.
