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

Answer:

340 Hz

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:

$f=\frac{v}{\lambda}=\frac{340}{1}=340 Hz$
