Question

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 718 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)	=
