H3-11. Tuning Forks And Resonant Tube
Purpose
To illustrate resonance in an air column.
Equipment
Plastic tube with resonant and non-resonant tuning forks.
Images
Description
Strike either tuning fork and hold it to the end of the tube. The sound intensity of the fork at the resonant frequency of the tube increases dramatically, whereas the fork with the non-resonant frequency does not become significantly louder. The second harmonic of the tube is excited.◙
