See Answer →Show that corresponding to any direction of propagation of electromagnetic wave in an anisotropic medium, there are two orthogonal plane (linearly) polarised plane waves which propagate, in general, with two different velocities.
See Answer →Write the expressions for two orthogonal plane polarised light waves propagating in z-direction and have equal amplitudes and phase difference of . Obtain the expression for the electric field of the resultant wave arising due to the superposition of these two waves. Determine the trajectory of the tip of the electric field vector associated with the resultant wave.
