Question

A turning fork as frequency 170HZ produces sound waves wavelength 2m calculate speed as sound

Answer 1

• Frequency=170Hz=f
• Wavelength=$\lambda$=2m
• Velocity=v=?

We know

$\boxed{\sf v=f\lambda}$

$\\ \sf\longmapsto v=170s^{-1}\times 2m$

$\\ \sf\longmapsto v=340ms^{-1}$

Answer 2

Explanation:

Wavelength=\lambdaλ =2m

Velocity=v=?

We know

\boxed{\sf v=f\lambda}

v=fλ

\begin{gathered}\\ \sf\longmapsto v=170s^{-1}\times 2m\end{gathered}

⟼v=170s

−1

×2m

\begin{gathered}\\ \sf\longmapsto v=340ms^{-1}\end{gathered}

⟼v=340ms

−1
