what is the frequency of sound in air with a wavelength of 150 cm

Sagot :

Answer:

f = 228.7 Hz

Explanation:

Given that,

The wavelength of sound in air, [tex]\lambda=150\ cm=1.5\ m[/tex]

We need to find the frequency of sound. The speed of any object is given by :

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

We know that the speed of sound in air is 343 m/s.

So,

[tex]f=\dfrac{v}{\lambda}\\\\f=\dfrac{343}{1.5}\\\\f=228.7\ Hz[/tex]

So, the frequency of sound is 228.7 Hz.
