Also, since the displacement is in the y direction, it is
often referred to as a y-polarised wave Since each point on the string
moves on a straight line, the wave is also referred to as a linearly polarised

wave Further, the string always remains confined to the x-y plane and
therefore it is also referred to as a plane polarised wave In a similar manner we can consider the vibration of the string in the
x-z plane generating a z-polarised wave whose displacement will be given
by
z (x,t) = a sin (kx – wt)
