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

Answer:

"332.8 m/s" is the right solution.

Explanation:

The given values are:

Wavelength,

$\lambda=0.65 \ m$

Frequency,

$f = 512 \ Hz$

As we know,

⇒  $Speed=Frequency\times Wavelength$

or,

⇒  $V=f\times \lambda$

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

⇒     $=512\times 0.65$

⇒      $=332.8 \ m/s$
