Set of Tuning Forks
Set of Tuning Forks
The Altay Set of Tuning Forks contains eight forks representing a full octave of frequencies, a soft protective case and a rubber mallet. You can also possible to study resonance, interference, beats and the relationship between them.
The set contains also tuning forks of exact multiple frequencies of each other (for example 256 kHz and 512 kHz), allowing you to perform interesting experiments in harmonics.
Ideal for use with LabPro software and data logging sound sensor to demonstrate beats.
Laws and principles investigated
experiment: Determine the sound frequency of the tuning forks
|
When tuning forks are vibrated, the forks create a compression and a rarefaction of the surrounding air.
Vibrating periodically the tuning fork alternatively compresses and rarefies the surrounding air that transmits this in the form of longitudinal waves that move away from source.
When these waves reach the ear they cause us to hear a sound.
This set of tuning forks are ideal in all the experiments useful to illustrate acoustic phenomenon, particularly with the Sonometer – Code 4316.00 and the Resonance Apparatus – Code 4331.27.
The diaphragm in a Microphone sensor records these variations by moving in response to the pressure changes.
The diaphragm motion is then converted to an electrical signal. Using a Microphone and a computer interface, you can explore the properties of common sounds like period, frequency and amplitude.
When two sound waves overlap, their air pressure variations will combine. For sound waves, this combination is additive. We say that sound follows the principle of linear superposition.
Beats are an example of superposition. Two sounds of nearly the same frequency will create a distinctive variation of sound amplitude, which we call beats.
You can study this phenomenon with a Microphone, lab interface, and computer.
