The magnetic field of a uniform plane wave that propagates in avacuum, is given by the expression:
B (r, t) = (10^−6 )[xˆ + 2yˆ + Bzzˆ] cos [ωt + 3x - y - z] inm.k.s.units and where xˆ, yˆ, zˆ are unit vectors along thecartesians axes . Find:
(a) The propagation direction.
(b) The wavelength λ.
(c) The angular frequency ω.
(d) The associated electrical field
