Description :-
For measuring the resonant length of an air column driven by a tuning fork.
Comprises a brass tube 292 x 27 mm diameter fixed to a base with a sliding inner tube 305 mm long which allows the length of the air column to be varied from 350 to 530 mm.
Description :-
On sturdy base, can be used in horizontal or vertical position. Prong size is 300 x 25 x 10 mm. Actuated by an electromagnet between the prongs, works with 6 V D.C. Amplitude of vibration can be varied by adjusting the position of the electromagnet.
Description :-
Hollow wooden sounding box 1290 x 130 x 110 mm, with mm scale, has two fixed bridges 72 cm apart over which wires are stretched.
To one wire is fitted a spring balance reading to 100 N x 5 N and its tension can be adjusted by a winged nut and measured.
Another wire passes over a pulley and can be loaded as desired.
A third wire, for comparison, can have its tension adjusted by a wrest-pin.
With 3 movable bridges, wrest-pin key, spring balance, and set of four wires of different diameters, each 1.5 meter long, without masses.
Description :-
Tuning Fork Activator is used as a surface to gently strike the tuning fork to activate vibrations.
Rubber activator is tapered so the bottom is wider for stability.
Made of solid rubber.
Description :-
Wooden baseboard 690 x 90 mm on four feet.
At one end are two 50 N spring balances with hooks and at the other are two wrest-pins.
With one large and two small bridges, wrest pin key and 2 steel wires, each 1 meter long, without masses.
Description :-
To study waves and to demonstrate compression, rarefaction, amplitude, wavelength, echoes, volume and pitch.
Inexpensive model for creating longitudinal/compression waves by simply pushing a Slinky along a track. Includes instructions.
