Most people are familiar with the fundamental mode of this device, which is the long-lasting mode used as a standard for pitch. The tuning forks were each milled from a single blank of fine steel and were then precisely tuned to produce a single, specific, tone. There are 2 steps to solve this one. As temperature increases the metal of the tuning fork will expand, and the result will be slightly longer fork prongs and hence a lower frequency (a longer wavelength) of vibration. Tuning forks have a very high "Q" of around 100, which is exactly the reason they go "hum" instead of "boing" when they are struck and why they are good frequency references, the point of all this talk. Strike the tuning forkwith a semi-hard object, e. As the tines of the tuning fork vibrate at their own natural frequency, they created sound waves that impinge upon the opening of the resonance tube.
