A sound wave is traveling at 6,420m/s and has a frequency of 600Hz. What is the wavelength?

GaryK [48]

Answer:

10.7 m

Step-by-step explanation:

Given that,

The speed of a sound wave, v = 6,420 m/s

The frequency of the wave, f = 600 Hz

We need to find the wavelength of the wave. We can find it using the below relation as follows :

$v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{6420}{600}\\\\\lambda=10.7\ m$

So, the wavelength of the sound wave is equal to 10.7 m.
