What is a bell jar?
What is a bell jar?A bell jar is a laboratory equipment used for creating a vacuum
How does the experiment work?
The experiment is done by placing an electrical bell in the bell jar.
As the air is pumped out of the sealed bell jar, the sound from the bell jar fades. At a particular vacuum, no more sound is heard from the bell, but we can see that the hammer continues hitting the gong and sound is produced. However, the sound is not audible to our ears because of the vacuum inside the jar.
hope this would help you!!
