🌊 Transverse vs Longitudinal Waves
All waves fall into one of two categories based on how particles vibrate relative to the direction the wave travels.
Transverse waves
Particles oscillate perpendicular (at right angles) to the direction of wave travel. Examples: light, water waves, all EM waves. You can see this in a rope — shake it side to side and the wave moves along while the rope itself only moves up and down.
Longitudinal waves
Particles oscillate parallel (along the same direction) to the direction of wave travel. They produce compressions (particles squashed together) and rarefactions (particles spread apart). Sound is a longitudinal wave — air molecules are pushed back and forth, not sideways.
