– In a longitudinal wave, particles of the medium vibrate parallel to the direction of wave propagation.
– This principle applies to both longitudinal and transverse mechanical waves; the medium oscillates but does not propagate. Electromagnetic waves also transmit energy and momentum through space without needing a physical medium, relying on oscillating fields.
