Homework Statement
Write down the (real) electric and magnetic field for a monochromatic plane wave of amplitude E0, frequency ω, and phase angle zero that is
(a) Travelling in the negative x direction and polarized in the z direction;
(b) Travelling in the direction from the origin to the point (1, 1, 1), with polarization parallel to the x, z plane.
In each case, sketch the wave, and give the explicit Cartesian component of the vectors k and n.
Homework Equations
Not Sure I have:
[tex] E(z,t) = E_0e^{kz - \omega t} [/tex]
and
[tex] B(z,t) = B_0e^{kz - \omega t} [/tex]
The Attempt at a Solution
See, I have the formulas above, But I am not sure wether or not they are the right formulas for this equation? For instance, it is in terms of z, but the question has the first part moving in the x-axis?
