A sound wave is traveling at 331 m/s and has a frequency of 126 Hz. What is the wavelength?​
damaskus [11]
<h2>Answer</h2>

2.626984127 m

<h2>Explanation:</h2><h2></h2>

You have to know the equation that relates wavelength, frequency, and velocity (it's like speed but a bit different).

v = f x λ

where:

v = velocity

f = frequency

λ = Wavelength

Rearrange to make λ subject:

λ = v / f

We've been given 331 as the speed, 126 as the frequency. Sub it into the equation:

331 / 126 = 2.626984127 m
