Question

What is the fundamental frequency of an open pipe of length 32.6cm if the velocity of sound in air is 334 m/s?

Answer 1

Here we use the formulae :

F = C / lambda

Where :

F = Frequency

C = Speed on air = 334 m / s

Lambda (Y) = Wavelength of sound in metres.

Convert the wavelength to m:

32.6 / 100 = 0.326 m

Substituting in the formula we have :

334 / 0.326 = 1024.54 Hz

Answer 2

Answer:

Explanation:

Here we use the formulae :

F = C / lambda

Where :

F = Frequency

C = Speed on air = 334 m / s

Lambda (Y) = Wavelength of sound in metres.

Convert the wavelength to m:

32.6 / 100 = 0.326 m

Substituting in the formula we have :

334 / 0.326 = 1024.54 Hz
