In a transverse wave, particles of the medium move perpendicular to the direction of wave propagation. This means that as the wave travels along a certain direction, the particles of the medium are displaced up and down. An excellent example of this is seen in ocean waves, where the surface of the water rises and falls as the energy of the wave moves across it.

This vertical movement creates crests (the highest points) and troughs (the lowest points) in the wave. Thus, the particles do not travel along with the wave; instead, they oscillate around a fixed position, leading to the characteristic pattern of a transverse wave. The other methods of particle movement—such as circular motion, back and forth (which describes longitudinal waves), or movement in a straight line—do not accurately describe the behavior of particles in a transverse wave.
