What is the difference between transverse wave and longitudinal wave?
In a transverse wave particles move perpendicular to the wave (light, string); in a longitudinal wave they move along it (sound).
In a transverse wave particles move perpendicular to the wave (light, string); in a longitudinal wave they move along it (sound). A reliable way to keep them apart is to focus on what each one is defined by, not just the similar-sounding words.
