Answer to Question #293111 in Optics for Chemistry

Question

If the magnetic field of a light wave oscillates parallel to a y axis and is given by By = Bm sin(k z − ωt), (a) in what direction does the wave travel and (b) parallel to which axis does

the associated electric field oscillate?

Answer 1

Given $By=Bmsin(kz−ωt)$ . According to this equation the direction of propagation is along z axis. The direction of electric vector must be perpendicular both y and z-axis, So it is along x-axis.
