Bell Experiment Apparatus For Physics
A bell jar experiment apparatus is a device that demonstrates how sound waves need a medium to travel. The apparatus typically includes:
An acrylic bell jar
A rubber stopper with lead plugs
An electric buzzer
A vacuum plate
A vacuum pump
A 3-6V DC power source
To perform the experiment, you:
Place the bell inside the bell jar
Pump air out of the jar to create a vacuum
Observe that the sound from the bell fades and eventually stops
Note that the hammer is still hitting the gong, but the sound is not audible
Reintroduce air to the jar and observe that the sound of the buzzer can be heard again
Bell jar experiments are often used in classrooms or by hobbyists. They can help students understand the properties of mechanical waves.
