As waves travel to shore
Waves might slow by reducing wavelength (L) or increasing period (T); observe that waves reduce L but keep T constant
- Wave height & kinetic energy remain constant (in fact waves that follow may add energy to waves already slowed)
- Crest heights of waves often increase
- Waves steepen, & often take on trochoidal form
- Energy of water particles in different parts of wave remains nearly constant
- Particles in upper parts of wave less affected by bottom, so keep circular path
