Musical Instruments

The students in my class play a set of pipes which I cut from a long plastic conduit pipe.
Each student takes a pipe representing one pitch and slaps one end of the pipe on cue.
The set of pipes is in tune with itself, but is sharp...

The simplistic calculation (length as a multiple of half-wavelengths) isn't good enough for a musical instrument because the antinode at the open end of the pipe is actually a bit beyond the end of the pipe (and finding this location is a dandy...

Hi everyone, need some realistic field notes on Organ Pipes National Park VIC. I am having trouble with finding field notes on the tessalated rocks and rosette rock at organ pipes, the notes i do find are RAR filed.

Thank you!

Hi, Em !

Gee, I am good to you!
I have been slaving here trying all sorts of magic to find an answer.

Organ pipe A, with both ends open, had a fundamental frequency of 300 Hz. The third harmonic of organ pipe B, with one end open, has the same frequency as the second harmonic of pipe A.

How long are (a) pipe A and (b) pipe B?
...

A both-ends-open pipe of length L resonates at a wavelength λ = 4L. λ = C/f. Thus L(A) = C/(4f) = 340/1200 m.
The 2nd harmonic of pipe A = 600 Hz. This is the 3rd harmonic of 200 Hz, so 200 Hz is the fundamental frequency of pipe B. A...

i would like to know how the vibrations (and sound waves) are changed by different types of pipe (different shape, length and width) leading to a different sound.

There are several different variables. The main one is size--the larger the pipe, the lower the resonance or pitch. Another is what the pipe is made of. Most organ pipes are made either of wood or metal, and that can have an effect. Even different...

Help please + Explain

When air molecules are at a higher temperature, they move faster, and they transmit sound more quickly. Conversely, when the temperature decreases, molecules move more slowly and transmit sound at a lesser speed.

The resonant...
