The wave equation for one component of the electric field in an electromagnetic wave is
Below are listed two situations and a number of statements about the field that solves this equation. For each of the situations A and B indicate which of the answers a-f must be true.
(A) The electromagnetic wave considered is approximately a plane wave traveling in the +z direction.
(B) The electromagnetic wave considered is approximately a single pulse (a rise of the magnitude of E from zero followed by a fall back to zero) moving in the -y direction.
