Longitudinal wave
from class: College Physics I – Introduction Definition A longitudinal wave is a type of wave where the particle displacement is parallel to the direction of wave propagation. Sound waves in air are a common example.
congrats on reading the definition of longitudinal wave . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test In a longitudinal wave, compressions and rarefactions occur along the direction of wave propagation. Sound waves are the most common examples of longitudinal waves. The wavelength in a longitudinal wave is the distance between two consecutive compressions or rarefactions. Longitudinal waves can propagate through solids, liquids, and gases. The speed of a longitudinal wave depends on the medium's elasticity and density. Review Questions What is the main characteristic that differentiates a longitudinal wave from a transverse wave? Name an everyday example of a longitudinal wave. How do compressions and rarefactions relate to wavelength in a longitudinal wave? "Longitudinal wave" also found in:
