A transverse wave travels along the Z-axis. The particles of the medium must move
पर्याय
along the Z-axis
along the X-axis
along the Y-axis
in the X-Y plane.

उत्तर
in the X–Y plane
In a transverse wave, particles move perpendicular to the direction of motion of the wave. In other words, if a wave moves along the Z-axis, the particles will move in the X–Y plane.
