Question

the windpipe of a typical whooping crane is about 5.0 ft. long. what is the lowest resonant frequency of this pipe, assuming it is closed at one end? assume a temperature of 37c.

Answer 1

The lowest resonant frequency of this pipe is approximately 58 Hz.

What is frequency?

Frequency is a measure of how often a particular event occurs or a certain value appears in a set of data. It is usually expressed as a number of occurrences or a percentage of the total. Frequency is a useful concept in statistics and probability theory as it can provide insight into the underlying data and help to draw conclusions about the data.

The speed of the sound is:

`$v =331 \sqrt{1 + (T)/(273) }`

`$v =331 \sqrt{1 + (37)/(273) }`

v = 352.72 m/s

The length of the pipe is:

L = 5.0 ft = 1.524 m

The wavelength is:

λ = 4L

= (4)(1.524)

= 6.096 m

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

`$ f =(352.72)/(6.096)`
