Question

On a cold day, the speed of sound in air is 330 m/s. A note with a frequency of 1,320 Hz is played on an instrument. What is the wavelength of that sound wave? 0.25 m 4 m 1,650 m 435,600 m

Answer 1

Answer:

0.25 m

Explanation:

Given that,

The speed of sound, v = 330 m/s

The frequency of the note of the instrument, f = 1320 Hz

We need to find the wavelength of the sound wave.

We know that,

Wavelength, $\lambda=\dfrac{v}{f}$

Put all the values,

$\lambda=\dfrac{330}{1320}\\\\\lambda=0.25\ m$

So, the wavelength of the sound wave is equal to 0.25 m.
