transverse wave
This term is primarily used in physics and acoustics to describe a specific mechanical behavior where the medium moves at a right angle to the energy flow. It is most frequently contrasted with longitudinal waves, such as sound waves in air, where the medium oscillates parallel to the direction of travel.
In practical application, the term is essential for describing light waves, seismic S-waves, and the vibration of strings. Because it describes a specific physical phenomenon, it is used almost exclusively in scientific, educational, or technical registers rather than in casual conversation.
Meanings
Examples
Light is a classic example of a transverse wave.
Unlike sound waves, a transverse wave does not require a longitudinal compression of the medium.
Is a transverse wave always perpendicular to the direction of travel?
The oscillation of the guitar string creates a transverse wave that produces sound.
