# Calculate the speed of sound on a day when a 1500 Hz frequency has a wavelength of 0.221 m.

The speed is 331.5 m/s.

See the step by step solution

## Step 1: Given Data

The frequency is f = 1500 Hz .

The wavelength is $\lambda =0.221\mathrm{m}$.

## Step 2: Explanation

The product of the wavelength and frequency of the wave gives us the velocity with which the wave is traveling.

## Step 3: Solution

The speed of a wave is given by,

$\mathbit{V}\mathbf{=}\mathbit{f}\mathbit{\lambda }$

For, $\lambda =0.221m$ and f = 1500 Hz ,

$v=1500Hz×0.2210m\phantom{\rule{0ex}{0ex}}=331.5m/s$

The velocity of the given wave is 331.5 m/s
