Answer:

The frequency, f, is 250 Hz. Hz is cycles per second. Hence a number divided by seconds.

The wavelength, λ, is 1.5 m.

The speed is v. Which is frequency times wavelength.

v = f xλ

Hence 250Hz*1.5m= 375 meters per second or 375 m/s

Explanation:

The expression for the speed of the sound in terms of frequency and the wavelength is as follows;

[tex]v=\nu \lambda[/tex]

Here, v is the speed, [tex]\nu[/tex] is the frequency of the wave and [tex]\lambda[/tex] is the wavelength of the wave.

It is given in the problem that a sound wave has a frequency of 250 Hz and a wavelength of 0.35 m.

Calculate the speed of the sound wave.

[tex]v=\nu \lambda[/tex]

Put [tex]\nu= 250 Hz[/tex] and [tex]\lambda= 0.35 m[/tex].

[tex]v=(250)(0.35)[/tex]

v= 87.5 m/s

Therefore, the speed of the sound wave is 87.5 m/s.
