The electric field of uniform plane wave is given by = 20 sin (2 x 10- ) + 20 cos (2 x 10 - ) . The polarization of wave is

Answer» The given two components are equal in amplitude, perpendicular and out of phase by 90°. ∴ The wave is circularly polarized. Now we consider z = 0 and put t = 0 and ∴ At t = 0, E = 10ay At t ∴ Left circularly polarized.
