How does the amount of water in a glass affect the pitch of the sound it produces?
The glasses with different amounts of water make different sounds. ... This is because the empty glass only has air around it, so the glass vibrates quickly when it is hit, causing the high pitch sound. The glass full of water causes the glass to vibrate slower, and the sound you hear is at a lower pitch.
