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

0.57 m

Step-by-step explanation:

The wavelength of a wave is given by:

`\lambda=(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=(600 wingbeats)/(1 s)=600 Hz` is the frequency of the wave

Substituting into the formula, we find the wavelength

`\lambda=(343 m/s)/(600 Hz)=0.57 m`
