The distance between two successive crests or troughs of sea waves is called as
Explanation
In oceanography, the horizontal distance between two successive crests or two successive troughs of a wave is defined as the wavelength [5]. The crest represents the highest point of the wave, while the trough is the lowest point [3]. While wavelength measures the horizontal span, wave height refers to the vertical distance from the bottom of a trough to the top of a crest [4]. Other related parameters include the wave period, which is the time interval between successive crests passing a fixed point, and wave frequency, which is the number of waves passing a point in a specific time interval [1]. Fetch, conversely, refers to the distance of open water over which the wind blows to generate waves. Therefore, the specific distance between two consecutive peaks or valleys is the wavelength.
