Question

which of the following is an example of longitudinal waves? sound waves water wave seismic waves light waves

Explanation:

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation. Sound waves are longitudinal waves because the particles of the medium (like air) vibrate back and forth parallel to the direction the sound wave travels. Water waves are a mix of transverse and longitudinal, seismic waves have both types (but primary seismic waves are longitudinal, but the option here is general seismic waves which is less straightforward), and light waves are transverse. So Sound Waves is the correct example.

Answer:

Sound Waves
