Question

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 1

219 m

Step-by-step 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

`\lambda=(v)/(f)\\\Rightarrow \lambda=(1530)/(7)\\\Rightarrow \lambda=218.57142857142\ m\approx 219\ m`

The wavelength of the T wave is 219 m
