Here is the further explanation taking option B in concern. You can clearly see, Obtion B will result in elliptical polarized wave. And as I promised, I have attached a diagram sho...
Option C is the best match for this question. even if Ax is not equal to Ay , then also option C could be the answer with some different slop. if you could solve the given equation...
we apply superposition principal when both waves are travelling in same direction but in this question both waves are perpendicular so there will be no superposition at all.
