Sound Waves & Oscillations

Catalogue No: 1120460/2

Comprises two matched nickel plated tuning forks of frequency A(426.6), each mounted on top of hollow wooden box open at one end. One fork is provided with a sliding mass on one prong by means of which its frequency can be varied from the nominal 426.6Hz. When both forks are sounded a clearly audible beat is produced, its rate depending upon the difference in frequency between the forks.

Catalogue No: 1120515

Useful to investigate the propagation of sound waves in a tube.
Features:
* Built-in Speaker
* Built-in Metric Scale
* Movable Microphone
* Movable Piston
Function generator can be used to operate the speaker and to create stable wave patterns at specified frequencies. Standing wave patterns in a closed tube or open tube can be observed and locate nodes & antinodes while varying the length of vibrating air column of the tube. Waveforms can also be observed in detail on oscilloscope.
