Physics 111-C21

Objective:

The objective of this laboratory was to measure the speed at which sound was traveling through the

air, using the resonance of longitudinal waves.

Equipment used:

1- Tall glass of water

1- PVC pipe, 10 in

1- Tape measure, 3 m

1- Mercury thermometer

1- Tuning fork, 384 Hz

1- Marker pencil

1- Block of wood

Data:

Data Table 1

Tuning fork frequency (Hz)

Length, L

Water level to top of tube (m)

d= diameter of tube (m)

?= 4(L + 0.3d)

(m)

Experimental

v=f?

(m/s)

Room Temperature (°C)

384

0.218

0.020

0.896

Calculations:

In order to find the value of ? (the wavelength), I used the following equation:

?= 4(L + 0.3d)

I then plugged the values from Data Table 1 in to find the sound wavelength.

?= 4 (0.218 m + 0.3 * 0.020 m)

?= 4(0.218 m +
