Chapter 9, Problem 14STP

To determine

The speed of the wave.

Answer to Problem 14STP

The speed of wave produced is $330\text{m}/\text{s}$ .

Explanation of Solution

Given info:

Vibrating frequency of tuning fork, $n=440\text{Hz}$

Wavelength of sound produced, $\lambda =0.75\text{m}$

Formula used:

The speed of a wave is given by the formula,

$v=n\lambda$

Calculation:

Substitute the given values in the above equation and calculate.

  $\begin{array}{l}v=440\times 0.75\text{m}/\text{s}\\ v=330\text{m}/\text{s}\end{array}$

Conclusion:

Thus, the speed of wave produced is $330\text{m}/\text{s}$ .
