Chapter 15, Problem 35A

To determine

To calculate: the speed of sound in freshwater witha frequency of $4.40\times {10}^2\text{ Hz}$ and a wavelength of $3.30\text{ m}$ .

Answer to Problem 35A

Speed of sound in freshwater = $1452\text{ m/s}$ .

Explanation of Solution

Given information:

Frequency of sound = $4.40\times {10}^2\text{ Hz}$

Wavelength of sound = $3.30\text{ m}$

Formula Used:

As per the relationship between wavelength, frequency and speed of a wave,

  $\lambda =v/f$

Where $\lambda$ is the wavelength of the wave, $v$ is the speed of the wave and $f$ is the frequency of the wave.

Calculation:

Now, putting values of $f=4.40\times {10}^2\text{ Hz}$ and $\lambda =3.30\text{ m}$ , we get $v=1452\text{ m/s}$ .

  $\lambda =v/f$

  $\lambda =3.30\text{ m}$

  $v=1452\text{ m/s}$

  $f=4.40\times {10}^2\text{ Hz}$
