Question

what best describes a transverse wave?
the displacement of particles is perpendicular to the direction of wave motion.
the displacement of particles is opposite to the direction of wave motion.
the displacement of particles is parallel to the direction of wave motion.
the displacement of particles is in the same direction of wave motion.

Explanation:

A transverse wave is defined by particle displacement perpendicular to wave motion. Options with opposite, parallel, or same - direction displacements do not match the transverse wave definition.

Answer:

The displacement of particles is perpendicular to the direction of wave motion.
