Resonance
Apparatus
with Telescopic
Brass Tube

of two brass tubes that can telescope
into each other, allowing the column of air
within the tube to be varied between 300 and 530mm.

Resonance Tuning Forks with Hammer
This apparatus can be used for demonstrating the production of beat frequencies.
It is comprised of two nickel-plated tuning forks mounted on individual sound
boxes. The two forks both produce an ‘A’ note (440Hz) when struck with the
mallet. One fork is provided with an adjustable mass, by means of which
the frequency of that fork may be shifted from the nominal 440Hz.
When both forks are sounded at the same time, a clearly audible
‘beat’ is produced, its rate depending upon the difference
in frequency between the two forks.
•
Used to hear dissonance
•
One fork adjustable
•
Supplied complete with 2x tuning forks, 1x adjustable
mass, 2x bases and mallet

Leslie’s Cubes
These Leslie’s cubes have sides with different
surface finishes. They are ideal for use in
experiments to show how objects emit and
absorb heat.
In use, the apparatus is filled with water which is
maintained at boiling point by a low Bunsen burner
flame. Infra-red sensors, etc., can be used to
compare the relative radiant heat output from each
of the four faces.
