Optics consider two wave represented by two mutually perpendicular electric vector.....

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...

kindly saw this in answer option B is given!!!!

option c is correct.... go through the solution...

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...

so superposition will occur when waves in same direction.

in our case neither frequency nor ampliitude are equal so option 3 is correct.

no interference will occur only standing will form. and this is only possible when frequency ana amplitude are approx equal

see the attached.

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.
