Uniform plane wave electromagnetics

Wave impedance for a uniform plane wave  is 120 pi

Uniform plane wave is travelling in z direction the electric field vector is in z direction electric field vector is a function of electric field vector components in x and y directions

The impedance of a wave is given by the ratio of modulus of the electric field vector to that of the magnetic field vector

Uniform plane wave is directed along the x-axis the electric and magnetic field vector along the x-axis will be zero
