Question

Have you ever blown across the top of a bottle and made a sound? If so, did you wonder how that sound was actually created? A bottle can be considered a type of air column. For this discussion, first find two empty bottles of different shapes or sizes. You will use these to try to make your own music.

Of the two bottles, which creates the higher note? Explain why that is the case.
Add enough water to one of the bottles so that they both will generate the same note. Explain what you did and why it worked.
Can you use beats to identify when the bottles are producing the same note? Explain the concept of beats in your own words.

Answer:

a) The bottle with the bigger size would create higher pitch because the bigger air space within the bottle the higher the pitch

b) By adding water i reduced the the air space in the bottle with higher pitch in a way that both bottles have same air space within them since the pitch of the bottle depends on the air space within them.

c) From my own understanding a beat can be defined as the rate or as the speed at which music is played,if we are to look at beat from the sound wave view point a beat is result from interference of two sound waves and if the wave are in phase that is if they are producing the same note (this means they are of the same frequency) then they would produce a higher sound (i.e is the resulting wave will be amplified ) but if they are not of the same frequency (i.e the both bottle does not generate the same note ) the they produce a lower sound (i.e the resulting wave would be noise)

Step-by-step explanation:

A bottle is a actually consider as the ' closed-end air column '. Some organs Pipes are the example of musical instruments that works in the same way. Actually the length of the bottle or the length of the closed end air column affect the pitch of the note.

Bottle with water(partially filled) will function as the closed-end air columns, which are basically tubes that are open at one end and closed or covered from others.

When playing a musical instruments that is closed-end air column like bottles, the pitch of the note depend upon the length of the air column means how much water are filled and how much empty space are there. The shorter the air column , the higher the frequency.
