Question



Zoom to view

A planar electromagnetic wave is propagating in the +x direction. At a certain point p and at a given instant, the electric field of the wave is given by E = (0.082 V/m) j . What is the magnetic vector of the wave at the point p at that instant? (c = 3.0 x 10 8 m/s) if an electromagnetic wave has components Ey = E0 sin (kx wt) and Bz = B0 sin (kx wt), in what direction is it traveling? if the magnetic field of an electromagnetic wave is in the + x-direction and the electric field of the wave is in the +y-direction, the wave is traveling in the

Explanation / Answer

1)

B = E/c = 0.082/3e8 = 0.27 nT k


2)

+x
