Question

A sound wave is moving through air. The wave has a wavelength of 0.65 m and a frequency of 512 Hz. Calculate the speed of the wave.​

Answer 1

"332.8 m/s" is the right solution.

Step-by-step explanation:

The given values are:

Wavelength,

`\lambda=0.65 \ m`

Frequency,

`f = 512 \ Hz`

As we know,

⇒
`Speed=Frequency* Wavelength`

or,

⇒
`V=f* \lambda`

By putting the given values in the above relation, we get

⇒
`=512* 0.65`

⇒
`=332.8 \ m/s`
