Energy Propagation - Group
Free-surface waves: linear superposition,
Superposition of linear plane
- Energy associated with wave motion.
For a single plane progressive wave:
Potential energy PE (per unit surface area of wave)
Kinetic energy (per unit surface area of wave):
Average wave energy E (over 1 period or 1 wavelength):
which is the Specific energy: total average wave energy per unit surface area.
