Identify the polarisation of the wave given, Ex = 2 cos wt and Ey = 2

1.	Identify the polarisation of the wave given, Ex = 2 cos wt and Ey = 2 sin wt. The phase difference is +90^0.(a) Left hand circularly polarised(b) Right hand circularly polarised(c) Left hand elliptically polarised(d) Right hand elliptically polarisedThis question was addressed to me by my school principal while I was bunking the class.I want to ask this question from Types of Polarization in division EM Wave Propagation of Electromagnetic Theory
Answer» The correct OPTION is (a) Left hand circularly polarised To EXPLAIN: The magnitude of the Ex and Ey COMPONENTS are the same. Thus it is circular polarisation. For +90 phase difference, the polarisation is left HANDED. In other words, the rotation is in clockwise direction. Thus the polarisation is left hand circular.
