Question

which of the following is an example of a longitudinal wave such as the one shown in this image?
sound
light

Explanation:

Longitudinal waves are waves in which the particles of the medium vibrate parallel to the direction of wave propagation. Sound waves are longitudinal waves as the air particles vibrate back - and - forth in the direction of the sound wave's travel. Light waves, on the other hand, are electromagnetic waves and are transverse in nature (the electric and magnetic fields oscillate perpendicular to the direction of wave propagation).

Answer:

sound
