In which of the following wave types is the particle motion perpendicular to wave motion?A longitudinal waveB p waveC surface waveD transverse wave

The particle motion is perpendicular to wave motion in a transverse wave (Option D).

Here's why:

A. Longitudinal waves: The particle motion is parallel to the wave motion. An example is sound waves in air.

B. P waves, or primary waves, are a type of seismic wave that also involves particle motion parallel to wave motion.

C. Surface waves: These waves travel along the surface of the earth (like those seen in water). The particle motion is both parallel (horizontal) and perpendicular (vertical) to the direction of wave propagation, in a elliptical path.

D. Transverse waves: The particle motion is perpendicular (at a right angle) to the wave motion. An example is waves on
