Question

The annoying sound from a mosquito is produced when it beats its wings at the average rate of 600 wingbeats per second. What is the wavelength of the sound….assume speed of sound is 343m/s through air. (three sigfigs, no units

Answer 1

Answer:

0.57 m

Explanation:

The wavelength of a wave is given by:

$\lambda=\frac{v}{f}$

where

$\lambda$ is the wavelength

v is the speed of the wave

f is its frequency

In this problem, we have

v = 343 m/s is the speed of a sound wave through air

$f=\frac{600 wingbeats}{1 s}=600 Hz$ is the frequency of the wave

Substituting into the formula, we find the wavelength

$\lambda=\frac{343 m/s}{600 Hz}=0.57 m$
