About this document
Sound Waves Cannot Travel in Vacuum by hassankashif405 is a document available to read on EtoBox.
The document describes an experiment to demonstrate that sound waves cannot travel in a vacuum by using a bell jar, vacuum pump and electric bell. Initially a clear sound can be heard but as the air is pumped out of the bell jar, the sound becomes fainter until it can no longer be heard, showing that sound requires a medium like air to travel.
