SUMMARY
The discussion centers on solving for the unknowns in the electric field vector E = 300i + 50j − 200k V/m and the magnetic field vector B = Bsub0 (1.7i − 3.9j + ak μT) in an electromagnetic wave. The key equations used are E = Bc and the Poynting vector formula s = (E x B) / (μ sub0). The values of a and Bsub0 can be determined using the dot product property E · B = 0 and the relationship between the magnitudes of E and B.
