1 M or m â prefix designating a number in thousands (not to be confused with SI prefix M for mega-or m for milli).
There are two types commonly referred to as: 'Shallow' and 'Deep' water. The differences are not only in the Frequency but also in the Beam Width and they are as follows: 'Shallow' water HST-WSBL 106-72 Transducer will operate on 2 frequencies on the HDS models: 200 (20Â°) & 83KHz (60Â°). 'Deep' water HST-DFSBL 106-77 Transducer will operate on 2 frequencies on the HDS models: 200KHz (12Â°) & 50KHz (35Â°).
Please review the following illustration, and then describe the condition under which a deep-water wave becomes a shallow-water wave? 21. What happens to wavelength as deep water waves become shallow water waves? 22. What happens to wave height as deep water waves become shallow water waves? 23. What happens to wave period as deep water waves become shallow water waves? 24. When the water depth is one-half the wavelength of a deep-water wave, water particles just above the bottom follow what kind of a path? 25.
