Lesson Topic
speed of sound lab
Lesson Outline
After a short explanation of resonance with sound waves, a lab was performed to determine the speed of sound in air using a resonance tube, tuning forks and millimeter measurements. The lab involves inserting a resonance tube into a cylinder of water, striking a tuning fork of known frequency, holding the tuning fork over the mouth of the tube and lifting the tube and fork until the loudest sound is heard. The measurement of the air column in the tube, conversion to meters,and the frequency of the fork are used to determine the speed of sound in air.
