The electrical field in a plane polarized wave is given by:
E = yE, cos(kz + wt)
where o>0 and the wavenumber, k = 4×10° m²’.
a. Find the wavelength of this wave.
b. What is the equation for the magnetic field carried by the wave? Explain your reasoning.
A. B = ŷ B, cos(kz+wt)
B. B = -& B, cos(kz + wt)
C. B = -î Bo sin(kz + wt)
D. B = & B, cos(kz + wt)
E. B = -ŷ B, cos(kz + wt)
c. Find the angular frequency, w, of the wave.
