Question: A standing electromagnetic wave with electric component E = Em cos kx cos wt is sustained along the x axis in vacuum. Find the magnetic

A standing electromagnetic wave with electric component E = Em cos kx ∙ cos wt is sustained along the x axis in vacuum. Find the magnetic component of the wave B (x, t). Draw the approximate pattern of the wave's electric and magnetic components (E and B) at the moments t = 0 and t = T/4, where T is the oscillation period.
