Electric Bell in Vacuum Jar Electric Bell in Vacuum Jar
S406-C

Nature, of course, abhors a vacuum - and sound waves won't travel through one. Prove it with a ringing bell inside a sealed glass jar. As air is gradually pumped out of the jar, the bell becomes faint, then dies. Includes jar, vacuum plate with valve, rubber seal, bell system, and instructions. You need a vacuum pump and two AA batteries (not included). Bell may be removed for other vacuum experiments. The inside height is 8", and the diameter is 8". Includes bell jar, electric bell, base plate with seal, and instructions.
Grades 6-12.
resonance tube MS218 Resonance Tube
S218
Determine the velocity of sound in air by measuring the resonant frequencies of an open tube.
Measure the signal distribution in a closed tube, calculate the wavelength and speed of sound from this data.
acoustic frequency MS212-2 Acoustic Frequency
S212-2

Acoustic resonance is the tendency of an acoustic system to absorb more energy when it is forced or driven at a frequency that matches one of its own natural frequencies of vibration (its resonance frequency than it does at other frequencies
acoustic frequency MS212-3 Acoustic Frequency
S212-3

Acoustic resonance is the tendency of an acoustic system to absorb more energy when it is forced or driven at a frequency that matches one of its own natural frequencies of vibration (its resonance frequency than it does at other frequencies
