Sound waves in air travel at approximately 330m/s. Calculate the frequency of a 2.5m-long sound wave.

Respuesta :

frequency = speed ÷ wavelength
= 330m/s ÷ 2.5m
= 132 Hz

The frequency of the sound wave with the given wavelength, traveling at the given speed is 132 Hertz.

What is Wavelength?

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

It is expressed as;

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given that;

  • Speed of the wave v = 330m/s
  • Wavelength λ = 2.5m
  • Frequency f = ?

λ = v ÷ f

2.5m = 330m/s ÷ f

f = 330m/s ÷ 2.5m

f = 132s⁻¹

f = 132Hz

Therefore, the frequency of the sound wave with the given wavelength, traveling at the given speed is 132 Hertz.
