Document Summary
Wavelength (l) distance for one full cycle (crest-to-crest, trough-to-trough) Wave height (h) - vertical distance from crest to trough. Wavelength (l) (m) distance between successive waves. Period (t) (s) time between successive waves. Period (t) (s) - time for one wavelength to pass a point (seconds per cycle) Frequency (f) number of waves per time (cycles per second) Celerity (c) wavelength/period (distance per time; meters per second). Water moves back & up, then forward and down in a circular motion (orbits) Energy passes through the water, but there is no net movement of the water. Each section of the rope goes up and down and returns to initial position, but the rope itself stays in place. It is only the disturbance imparted to the rope by shaking its end that moves as a wave. The matter transfers the energy as it passes by the rope and stays in position.
