Transverse waves
1. Particles vibrate in the direction
perpendicular to the direction of wave
propagation.
2. The wave propagates in the form of
crests and troughs.
3. One crest and one trough constitute a
wave.
Ex: Light waves, waves on the surface of
water, waves on a string
Longitudinal waves
1. Particles vibrate along the direction of
the propagation.
2. The wav propagates in the form of
compressions and rarefactions.
3. One compression and one rarefaction
constitute a wave.
Ex: Sound waves, vibration in gases,
oscillation of spring.
