Question

Sound travels at 340 m/s in dry air at room temperature. What is the

wavelength of sound waves with a frequency of 880 Hz under those
conditions?

Answer 1

Wavelength of sound waves
`\ambda = 386` millimetres

Step-by-step explanation:

The speed of any wave is equal to the product of its wavelength and frequency.

This can be represented mathematically as

`V = f* \lambda`

Where

V is the speed of sound waves

f is the frequency of sound waves

and

`\lambda` is the wavelength of the sound waves.

Substituting the given values in above equation we get -

`340 = f * \lambda\\\lambda = (340)/(880) \\`

`\lambda = 0.386` meters

`\ambda = 386` millimetres
