At some instant and location, the electric field associated with an electromagnetic wave in vacuum has the strength 80.7 V/m. Find the magnetic field strength B, the total energy density u, and the power flow per unit area, all at the same instant and location. B = power flow per unit area: T W/m² u= J/m³
