Question

A sound wave is traveling at a speed of 330 m/s. If the frequency of the wave is 660 Hz, what is the wavelength of the sound wave?

2 m
330 m
990 m
0.5 m

Answer 1

Answer:

The wavelength of the sound wave traveling at 330 m/s is 0.5 m.

Explanation:

Given:

Speed of sound wave is, $v=330\ m/s$

Frequency of the sound wave is, $f=660\ Hz$

Speed of a sound wave is related to its frequency and wavelength as:

$v=f\lambda$, where, $\lambda$ is the wavelength.

Now, plug in 330 for $v$, 660 for $f$ and solve for $\lambda$. This gives,

$330=660\lambda\\\lambda=\frac{330}{660}=0.5\ m$

Therefore, the wavelength of the sound wave traveling at 330 m/s is 0.5 m.
