Question

What is the wavelength of this sound in the air?

Cicadas produce a sound that has a frequency of 144 Hz. What is the wavelength of this sound in the air? The speed of sound in air is 300 m/s.

Answer 1

`"2.083 m"`

Explanation:

Frequency, speed and wavelength are related as

`"v = f λ"`

`λ = "v"/"f" = "300 m/s"/"144 Hz" = 25/12\ "m = 2.083 m"`
