A bottle that is fully filled produces a sound whose pitch compared to a half filled bottle will be:
Half
Lower
Same
Higher
A fully filled bottle has a least air column and hence vibrates with high frequency.
Case 1: A bottle is fully filled with water and a hole is made at the bottom. Case 2: A bottle is fully filled with water and a hole is made in the middle of it. In which case, the water comes out with greater pressure?
Fill a glass bottle with some water. Blow across the mouth of bottle and listen to the sound. Change the level of the water in the bottle. Does the pitch of the sound change?
Please explain the relation between the amount of water in the glass and the pitch of the sound produced on blowing over the glass with diagram and a short video also. Thank you.
