A closed organ pipe has a length of 2.40 m?

In summary, the conversation is about a problem involving a closed organ pipe with a length of 2.40 m and a frequency of 35.7 Hz. When a second pipe is played at the same time, a 1.40 Hz beat note is heard, leading to the question of how much longer the second pipe is. The person asking the question is new and unsure of where to post their question, and asks for help in solving both parts of the problem. However, the expert summarizer cannot provide an answer without more information on the relevant equations and the individual's attempts to solve the problem.

A closed organ pipe has a length of 2.40 m.

a.) What is the frequency of the note played by the pipe? Use
343 m/s as the speed of sound.

b.) When a second pipe is played at the same time, a 1.40 Hz beat note is heard.
By how much is the second pipe too long?

The a.) problem's solution is 35.7 Hz. and b.) problem's solution is 0.10 m

The actual problem here is that I don't know how to properly solve b.)

I'm lost... I'm new here.I just don't know here to post my question lol. I wasn't trying to solve this problem. Can you guys help me and tell me how to solve both of a.) and b.)and tell me where can I post this question if this was the wrong section.Thanks in advanced :)

This is the correct section.So as the Mentor said,
- What are the relevant equations for this problem?
- What have you done to try to solve the problem?

Only then will we be able to help you.Sorry :frown:
If that was a question given to you,you must be knowing some relevant equations or some method to solve it.
 

FAQ: A closed organ pipe has a length of 2.40 m?

1. How does the length of a closed organ pipe affect its sound?

The length of a closed organ pipe determines the wavelength of the sound it produces. This, in turn, affects the pitch of the sound. Longer pipes produce longer wavelengths and lower pitches, while shorter pipes produce shorter wavelengths and higher pitches.

2. What is the relationship between the length of a closed organ pipe and its resonant frequency?

The resonant frequency of a closed organ pipe is inversely proportional to its length. This means that longer pipes have lower resonant frequencies and shorter pipes have higher resonant frequencies. This relationship is known as the fundamental frequency or first harmonic.

3. How does the length of a closed organ pipe compare to an open organ pipe?

A closed organ pipe is twice the length of an open organ pipe producing the same pitch. This is because a closed pipe has both ends sealed, while an open pipe has one end open. This difference in length affects the wavelength of the sound produced.

4. Can the length of a closed organ pipe be changed to produce different notes?

Yes, the length of a closed organ pipe can be changed to produce different notes. By adjusting the length of the pipe, the wavelength and pitch of the sound can be altered. This is often done by opening or closing holes along the length of the pipe.

5. How does the length of a closed organ pipe affect its harmonics?

The length of a closed organ pipe affects the harmonics it produces. The length determines the wavelengths of the harmonics and therefore their frequencies. Longer pipes have longer harmonics with lower frequencies, while shorter pipes have shorter harmonics with higher frequencies.
