Question

a wave in which particles move perpendicular to the direction that the wave itself is traveling. light wave, longitudinal wave, sound wave, transverse wave

Explanation:

Transverse waves are defined as waves where particles move perpendicular to the wave - propagation direction. Light waves are a type of transverse wave but the description directly matches the general definition of transverse waves. Longitudinal waves have particles moving parallel to the wave direction and sound waves are longitudinal waves in air.

Answer:

D. Transverse wave
