Question

Consider a pipe of length 80.0 cm open at both ends. What is the lowest frequency f of the sound wave produced when you blow into the pipe?

Answer 1

`f = 214.375\ Hz`

Step-by-step explanation:

Given,

Length of the Pipe, L = 80 cm

Frequency ,f = ?

Speed of sound, v = 343 m/s

Wavelength when pipe is open at both the ends

`\lambda = 2 L`

`\lambda = 2* 80 = 160\ cm = 1.6\ m`

Fundamental frequency

`f =(v)/(\lambda)`

`f =(343)/(1.6)`

`f = 214.375\ Hz`
