In this experiment I
have taken a tuning fork, a hollow tube and a measuring cylinder filled with
water. The hollow tube can move up and down creating a length of air in the
column above the water. The tuning fork is placed over the column and the
column moved up and down until the loudest sound is heard. The length of the
tube is a quarter of the wavelength, so we multiply the column length by 4.
We know that the
velocity = frequency x wavelength
So if the column is
19.4cm long then the wavelength is 19.4 x 4 = 77.6
The frequency of the
tuning fork is 440Hz
So the velocity =
0.776 x 440 = 341.44 m/shttps://www.youtube.com/watch?v=G7yl43Zvy8E
