Answer:
λ = 22.667 m
Explanation:
The range of frequency (f) of sound wave = 15 Hz to 50 KHz
Temperature (T) = 20 °C
Speed (v) of sound = 344 m/s
Lets assume, wavelength corresponding to the lower cut-off point of the sounds= λ
We know that, the speed (v), frequency (f) and wavelength (λ) are related as
[tex]v = f \times \lambda[/tex]
So,
[tex]\lambda = \frac{v}{f}[/tex]
[tex]\lambda = \frac{340}{15}[/tex]
λ = 22.667 m
