Aplane monochromatic electromagnetic wave with wavelength λ = 2.2 cm, propagates through a vacuum. its magnetic field is described by
where bx = 3.1 x 10-6 t, by = 3.4 x 10-6 t, and i-hat and j-hat are the unit vectors in the +x and +y directions, respectively.
1) what is f, the frequency of this wave?
2) what is i, the intensity of this wave?
3) what is sz, the z-component of the poynting vector at (x = 0, y = 0, z = 0) at t = 0?
4) what is ex, the x-component of the electric field at (x = 0, y = 0, z = 0) at t = 0?
5) Compare the sign and magnitude of Sz, the z-component of the Poynting vector at (x=y=z=t=0) of the wave described above to the sign and magnitude of SIIz, the z-component of the Poynting vector at (x=y=z=t=0) of another plane monochromatic electromagnetic wave propagating through vaccum described by: ω where BIIx = 5.5 X 10-6 T, BIIy = 3.4 X 10-6 T, and i-hat and j-hat are the unit vectors in the +x and +y directions, respectively.
siiz < 0 and magnitude(siiz) ≠ magnitude(sz)
siiz < 0 and magnitude(siiz) = magnitude(sz)
siiz > 0 and magnitude(siiz) ≠ magnitude(sz)
siiz > 0 and magnitude(siiz) = magnitude(sz)
