Sound waves are a - Transverse b - Longitudinal c - Transverse and longitudinal

hey sally!

Explanation:

Sound waves are C) Transverse and longitudinal.

We can say that a wave is produced by the vibrations of the particles of the medium through which it passes.

There are two types of waves: Longitudinal waves and Transverse waves.

Longitudinal Waves: A wave in which the particles of the medium vibrate back and forth in the 'same direction' in which the wave is moving. Medium can be solid, liquid or gases. Therefore, sound waves are longitudinal waves.

Transverse Waves: A wave in which the particles of the medium vibrate up and down 'at right angles' to the direction in which the wave is moving. These waves are produced only in a solids and liquids but not in gases.
