Which of these uses sound waves to locate underwater objects?

• radar

• telescope

• sonar

A stereo speaker is made of a flexible cone-shaped material that vibrates, creating a sound wave. A sound wave formed by a speaker travels through air to your ear as a series of compressions and rarefactions of air molecules.

Which statement classifies the sound wave?

• longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion

• transverse wave in which the particles of the wave move in a direction perpendicular to the wave motion

• transverse wave in which the particles of the wave move in a direction parallel to the wave motion

• longitudinal wave in which the particles of the wave move in a direction perpendicular to the wave motion
