Question

Question 7 At a particular point in time and space, the electric field component of a plane wave is pointed in the positive x-direction, while the magnetic field is directed in the positive z-direction. The plane wave is therefore propagating in which vector direction? a.+ X Direction b.- X Direction c. + Y Direction d.- Y Direction e.+ Z Direction f. - Z Direction Question 8 At a particular point in time and space, the magnetic field component of a plane wave is pointed in the positive x -direction, while the plane wave is propagating the positive z -direction. The electric field component of this plane wave is then pointed in which vector direction? a.+ X Direction b.- X Direction c. + Y Direction d.- Y Direction e.+ Z Direction f. - Z Direction Question 9 Determine the polarization of the following plane wave, given the phasor representation of its electric field components at (t, x, y, z)= 0. Vector E=Eo e^j(Omegat-kz)( -3 x bar+ yBar) a. Linear b. Right-hand circularly polarized (RHCP) c. Left-hand circularly polarized (LHCP) d. Right-hand elliptically polarized e. Left-hand elliptically polarized
