3.E 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.
4.Light, sound, and waves in the ocean are common examples of waves.
5.In the periodic wave shown in the diagram above, the highest point is called the crest
