For years, marine scientists 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 they traced the source to underwater volcanoes, whose rising columns of bubbles resonated like organ pipes.
A typical T wave has a frequency of 7 Hz. Knowing that the speed of sound in seawater is 1530 m/s, show that the wavelength of a T wave is 219 m.

Answer:

219 m

Explanation:

v = Speed of sound in water = 1530 m/s

f = Frequency of the sound wave = 7 Hz

The wavelength of a wave is obtained when the speed of the wave is divided by the frequecy of the wave

[tex]\lambda=\frac{v}{f}\\\Rightarrow \lambda=\frac{1530}{7}\\\Rightarrow \lambda=218.57142857142\ m\approx 219\ m[/tex]

The wavelength of the T wave is 219 m
