Question

(a): Determine the wavelength of sound when the intensity of sound gets reduced from its maximum when speaker one moves at a distance of 0.16m .

Short answer

The wavelength of sound is 0.32m .

Step-by-step solution

Find the value of λ

The intensity of sound gets reduced from its maximum when speaker one moves 0.16m.

The distance between the maximum amplitude and the minimum amplitude of the wave is as follows:

Distance $=\frac{\lambda }{2}$

Where,

-$\lambda$is the wavelength.

Rearrange the above equation as follows:

$\lambda =2\text{(Distance)}$

The value of the distance is 0.16m .

Substitute this value in the above equation.

$$\begin{gathered} \lambda =2\left(\text{Distance}\right) \\ =2(0.16\text{m}) \\ =0.32m \end{gathered}$$

Thus, the wavelength of sound is$0.32m$ .
