Question

IN EM waves, polarization ___________

(a) is always vertical

(b) is caused by reflection

(c) is due to transverse nature of waves

(d) is due to longitudinal nature of waves

I have been asked this question by my school principal while I was bunking the class.

My question is based upon Demodulation of SSB with Large Carrier topic in division SSB Modulation of Analog Communications

Answer 1

Right answer is (c) is due to transverse nature of waves

Easy explanation: In electromagnetic waves, polarization is mainly due to the transverse nature of waves only. Transverse nature of electromagnetic waves mean that the electric and magnetic fields are perpendicular to each other as well as perpendicular to the direction of propagation of waves.
