The book grapples with issues related to the recent worldwide shift to remote teaching. WebE is the electric field vector, and B is the magnetic field vector of the EM wave. For electromagnetic waves E and B are always perpendicular to each other and perpendicular to the direction of propagation. The direction of propagation is the direction of E x B. If, for a wave traveling in the x-direction E = E j, then B = B k and j x k = i . crystal report in windows form application c#
