1.	An Em wave is said to be vertically polarized when the angle between the electrical field and earth is _______(a) 50°(b) 20°(c) 90°(d) 180°This question was addressed to me in an online quiz.I would like to ask this question from Antenna Fundamentals topic in chapter Antennas and Wave Propagation of Avionics
Answer» The correct choice is (c) 90° Easy explanation: Polarization refers to the ORIENTATION of MAGNETIC and electric fields with respect to the earth. If an electric field is parallel to the earth, the ELECTROMAGNETIC WAVE is said to be horizontally polarized; if the electric field is perpendicular to the earth, the wave is vertically polarized.
