Question

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

Answer 1

Answer:

f = 228.7 Hz

Explanation:

Given that,

The wavelength of sound in air, $\lambda=150\ cm=1.5\ m$

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

$v=f\lambda$

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

So,

$f=\dfrac{v}{\lambda}\\\\f=\dfrac{343}{1.5}\\\\f=228.7\ Hz$

So, the frequency of sound is 228.7 Hz.
