Write equations for both the electric and magnetic fields for an electromagnetic wave in the red part of the visible spectrum that has a wavelength of 699 nm and a peak electric field magnitude of 3.6 v/m. (use the following as necessary: t and x. assume that e is in volts per meter, b is in teslas, t is in seconds, and x is in meters. do not include units in your answer. assume that e = 0 and b = 0 when x = 0 and t = 0.)e(x, t)= b(x, t)=
