A plane electromagnetic wave traveling in the +ve direction of an x axis in vacuum consists of components Ex = Ey = 0 and Ez = (5.0 V/m) cos[(p × 1015 s-1)(t - x/c)].
(i) Determine the amplitude of the magnetic field component?
(ii) Parallel to which axis does the magnetic field oscillate (enter 1 for x axis, 2 for y axis and 3 for z axis)?
(iii) If the electric field component is in the positive direction of the z axis at a certain point P, determine the direction of the magnetic field component there (enter 1 for x axis, 2 for y axis and 3 for z axis. For opposite direction use minus sign)? Suppose that the speed of light is around 2.998*108 m/s.
