Question

Suppose you wanted to produce a sound wave with a wavelength of 1m

in room temperature air. What would its frequency be? *​

Answer 1

340 Hz

Step-by-step explanation:

The frequency of a wave is the number of oscillations completed by the wave per second.

For a wave, the relationship between wavelength of the wave and its frequency is given by the wave equation:

`v=f\lambda`

where

v is the speed of the wave

f is its frequency

`\lambda` is its wavelength

In this problem, we have a sound wave, with wavelength of

`\lambda=1m`

The speed of sound waves at room temperature is

`v=340 m/s`

Therefore, using the previous equation, we can find the frequency of the wave:

`f=(v)/(\lambda)=(340)/(1)=340 Hz`
