Question
Explain whether sound waves are transverse or longitudinal, and what this means.
Solution
Sound waves are longitudinal waves, not transverse waves.
To understand what this means, we first need to define both types of waves:
-
Transverse Waves: In these waves, the direction of the oscillation is perpendicular to the direction of motion of the wave. A common example of a transverse wave is a wave on a string where the displacement of the string is perpendicular to the direction of the wave.
-
Longitudinal Waves: In these waves, the direction of the oscillation is the same as the direction of motion of the wave. A common example of a longitudinal wave is a sound wave.
In the case of sound waves, when they travel through a medium, the particles of the medium vibrate in the same direction as the motion of the wave, making sound waves longitudinal. For example, when sound travels through air, it compresses and rarefies the air molecules in the same direction in which the sound is moving. This creates areas of high pressure (compressions) and low pressure (rarefactions) that move through the air, carrying the sound with them.
