Question: A plane electromagnetic wave traveling in the positive direction of an x axis in vacuum has components Ex = Ey = 0 and E z

A plane electromagnetic wave traveling in the positive direction of an x axis in vacuum has components Ex = Ey = 0 and E z = (2.0 Vim) cos [(π x 1015 s-1) (t – x/c)].

(a) What is the amplitude of the magnetic field component?

(b) Parallel to which axis does the magnetic field oscillate?

(c) When the electric field component is in the positive direction of the z axis at a certain point P, what is the direction of the magnetic field component there?
