What is the wavelength of a soundwave wave with a frequency of 256 hertz?

Answer 1

The speed of sound c is wavelength lambda times frequency f. The speed of sound in air of 20 degrees Celsius or 68 degrees Fahrenheit is 343 meters per second. Wavelength lambda = Speed of sound c divided by frequency f. The wavelength is 343 / 256 = 1.34 meters.

Answer 2

Taking the speed of sound as 340.29 metres per second.

if: velocity (metres/sec) = wavelength (metres) * frequency (cycles per second)

then:

wavelength = velocity / frequency = 340.29 / 20,000 = 0.017 metres

Answer 3

You need to divide the speed of the wave by the frequency, to get the wavelength. Unfortunately, the speed of a sound wave is not a unique number; it depends on several factors, including the material; in the case of air, it depends on the temperature and humidity. But according to the Wikipedia, at 20 °C, and in dry air, the speed of sound is approximately 344 meters/second - you can use this as a reference value.

Answer 4

That varies with the medium. The faster the speed of sound in a medium, the longer the wavelength in that medium.

Answer 5

At the typical sea-level speed of sound of 340 m/s, it would be 17 meters.
