For years, marine scientist were mystified by sound waves detected by underwater microphones in the pacific ocean. these so-called t waves were among the purest sounds in nature. eventually the researchers traced the source to underwater volcanoes whose rising columns of bubbles resonated like organ pipes. a typical t wave has a frequency of 6.8 hz. knowing that the speed of sound in seawaver is 1,530 m/s, determine the wavelength of a t wave.
