Question

The speed of sound traveling through a dense material is 600 m/s. If the wavelength is 15.0 m, what is the frequency of this sound?9,000 Hz80 Hz0.0025 Hz40 Hz

Answer 1

W0e are asked to determine the frequency of a sound given its velocity and wavelength. To do that we will use the following formula:

`v=\lambda f`

Where:

`\begin{gathered} v=\text{ velocity} \\ \lambda=\text{ wavelength} \\ f=\text{ frequency} \end{gathered}`

Now, we solve for the frequency by dividing both sides by the wavelength.

`(v)/(\lambda)=f`

Now, we substitute the values:

`(600(m)/(s))/(15m)=f`

Solving the operations:

`40Hz=f`

Therefore, the frequency is 40 Hz.
