An 800-kHz radio signal is transmitted from a radio tower and is
detected 2.7 km from that tower. The detected electric field
amplitude of the signal is 0.36 V/m. Assume that the signal
power is radiated uniformly and that the ground absorbs signals
completely. (c = 3.0 × 10^8 m/s, μ0 = 4π × 10^-7 T ∙ m/A, ε0 = 8.85
× 10^-12 C2/N ∙ m2)
What is the intensity of the EM wave at that point?
