In this image , direction of electric field vector is along y axis and direction of magnetic field is along x axis . But if we write direction of electric field vector and magnetic field vector as along x and y axis respectively, would it be correct? Or is it compulsory that when a wave propagates along z axis, the directions have to be those that are shown in the figure?
