Period: the time it takes for two successive crests to pass a given point. Frequency: the number of waves passing a point in a given amount of time, usually expressed as waves per second. This is the inverse of the period. Speed: how fast the wave travels, or the distance traveled per unit of time.

19 Δεκ 2021 · We can broadly define ocean waves as all sea-surface variations on the timescale of seconds to months as generated in the oceans. MSL is the sea level you get if you average these fluctuations out. This definition of ocean waves includes wind waves, tides and tsunamis.
Humans generally hear sound waves whose frequencies are between 20 and 20,000 Hz. Below 20 Hz, sounds are referred to as infrasonic, and above 20,000 Hz as ultrasonic. The frequency of middle “C” on a piano is 246 Hz. Wavelength is the distance between two peaks of a sound wave.
The wave travels a distance of one wavelength in a time equal to one period. The wave speed is thus the distance over the time, . Instead of writing the equation in this form, however, we generally use the fact that the frequency, f, of the oscillation is the inverse of the period, . This leads to the equation in the box below.
The period T is the time it takes one wavelength or two consecutive troughs (or crests or any other wave reference point) to pass by a fixed position. The speed C (C stands for celerity) of the wave is the quotient of the wavelength over period. Figure 1.
21 Φεβ 2017 · The average peak in the cross correlation lies at a lag time of 85.5 s, which corresponds to a horizontal propagation velocity of 1477 m s −1 (the distance between N2 and S2 is 126.3 km). Only the positive lag times are resolved, since no clear persistent peak is found around −85.5 s.
