Progressive waves
As progressive wave moves through water, different water parcels occupy crest at different times
Frequency (F) of wave is the number of crests or troughs that pass a point per unit time
- Measure frequency in cycles per second
Period (T) of wave is the time interval between the passage of successive crests or troughs
Wave speed (C) = wavelength divided by period (C= L/T)
Wave speed (C) wavelength times frequency (C = LF)
