Question

Compare the properties of sea waves (say deep water) with those of acoustic pressure waves. How can the to-and-fro motion of an acoustic wave be described as a sine wave? How are acoustic frequency and acoustic wavelength affected by ambient conditions (temperature, salinity and pressure)? Calculate the acoustic velocity in water of temperature 12.2degree C, salinity 34.5 and mean depth 74m. In 1827 Colladon & Sturm measured the acoustic velocity as 1435 ms^-1 in fresh water at 8.1degree C. How good a measurement was this?
