A plane monochromatic electromagnetic wave with wavelength = 4.6 cm, propagates through a vacuum. Its magnetic field is described by B=(Bxi+Byl)cos(kz+wt) where w = omega, Bx = 1.4e-6, By = 5.2e-6 T
and i-hat and j-hat are the unit vectors in the +x and +y directions, respectively.
What is Ex, the x-component of the electric field at (x = 0, y = 0, z = 0) at t = 0?
By*c = 5.2e-6*3e8.
