Resonance

Apparatus

with Telescopic

Brass Tube

This resonance apparatus is comprised

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.

Outer tube fits into base

Eisco type PH0718B

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

Eisco type PH0742A

Tuning Forks Set

An eight-piece set of nickel-plated

tuning forks with plain shanks. The

forks are marked with their individual

frequencies: C (256Hz), D (288Hz),

E (320Hz), F (341Hz), G (384Hz), A

(426Hz), B (480Hz) and C (512Hz).

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.
