The electric field of an electromagnetic wave is given by \(\rm \vec{E}=3 \sin (k z-\omega t) \hat{i}\) + \(\rm 4 \cos (k z-\omega t) \hat{j}\). The wave is
1
linearly polarised at an angle \(\tan ^{-1}\left(\frac{4}{3}\right)\) with the X-axis.
2
linearly polarised at an angle \(\tan ^{-1}\left(\frac{3}{4}\right)\) with the X-axis.
3
elliptically polarised in clockwise direction and it is travelling towards the observer.
4
elliptically polarised in counter clockwise direction and it is travelling towards the observer.
