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.
