What is the frequency of a sound wave with a wavelength of 0.04 meter in air? What type of wave is this, transverse or longitudinal

May 29, 2018

$\text{8500 Hz}$ and longitudinal

Explanation:

Speed ($\text{v}$), frequency ($f$) and wavelength (λ) are related as

"v"= f λ

Speed of sound at $\text{20°C}$ is approximately $\text{340 m/s}$

$f = \text{v"/λ = "340 m/s"/"0.04 m" = "8500 Hz}$

Sound wave is longitudinal.
