Question

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.

Answer 1

225 m

Step-by-step explanation:

`f` = Frequency of the T wave = 6.8 Hz

`v` = Speed of sound in seawater = 1530 ms⁻¹

`\lambda` = Wavelength of the T wave

we know that, frequency, speed and wavelength are related as

`wavelength = (speed)/(frequency)`

`\lambda = (v)/(f)`

Inserting the values, we get

`\lambda = (1530)/(6.8)\\\lambda = 225 m`
