1. The problem statement, all variables and given/known data A point-like source of electromagnetic waves radiates power uniformly in all directions at a single frequency. At a distance of 5.6 km from the source, a detector measures the intensity (energy flux density) of the wave to be 35.1 μW/m2 (microwatts per square meter). a)Calculate the amplitude of the magnetic field oscillations of the wave at the detector. b)What is the total power radiated by the source? Hint: The intensity (power/area) is c ε0 E0^2/2 where E0 is the amplitude of oscillation of the electric field in the wave. Then the magnetic field is B0=E0/c. 2. Relevant equations The relevant equations are given in the "Hint" of the problem. And I used 8.85E-12 for epsilon. 3. The attempt at a solution I got 0.163 T for the amplitude, but it is wrong. I got 1.425E-12 W for the power, but it is also wrong. Help please.
