In an EM wave traveling west, the B field oscillates
Chapter 31, Problem 4P(choose chapter or problem)
In an EM wave traveling west, the B field oscillates vertically and has a frequency of 80.0 kHz and an rms strength of \(6.75 \times 10^{-9} \mathrm T\). What are the frequency and rms strength of the electric field, and what is its direction? [Hint: see Fig. 22-7.]
