Question

A sound wave with a frequency of 2.0 kilohertz is traveling through the air at stp determine the wavelength?

Answer 1

`color(blue)(0.16565m)`

Explanation:

Frequency `=f`

Wave speed `=v`

Wavelength `=lambda`

`v/f=lambda`

Speed of sound at stp `=331.3ms^(-1)`

`lambda=(331.3ms^(-1))/(2000s^(-1))=0.16565m`
