A tuning fork resonates ever a open pipe at 30 cm.What is the longest wavelenght the sound from the open pipe?

Question

can have?If the pipe is closed on one end and the tuning fork resonates at 30 cm,what is the longest wavelenght the sound fronm the closed pipe can have?

Answer 1

The longest wavelength is twice the length of the pipe, or 60 cm. See the ref. For a closed pipe the longest wavelength is 4 times the pipe length or 120 cm. Assuming the velocity of sound is 340.29 m/s, these wavelengths correspond to frequencies of 567.15 Hz and 283.575 Hz respectively.

Answer 2

incredibly basic: a million. turn off the water to the abode 2. pass as some distance down the pipe as you could pass with out beginning up partitions and ceilings. 3. decrease the pipe. 4. set up a 'T' setting up. 5. To the 'T' setting up connect a short length of pipe. 6. set up a cap to the suited of that pipe. 7. turn the water on. 8. If the noise isn't long previous, pass to a distinctive spot interior the abode and do the comparable element to any chilly water pipe. often you will locate get entry to close to the bathing gadget plumbing. What you're doing is trapping a small volume of air interior the lines that acts as a cushion to water hammers. you could not compress a liquid so the pipe could desire to pass each and every time there's a tension surge. With the air trapped there, this is going to compress instead of the pipe moving and making all that noise. you could pass to a commercial plumbing grant and purchase a gadget particularly for this purpose. It installs lots the comparable way different than that it has a spring in it. i would not pass by way of the rate in the previous only setting up my approach. in the previous you do any of this or evaluate your interest finished, pass seem to work out the place the noise grew to become into happening. there is a few chaffing of the pipe and a few placed on that could finally develop right into a leak. conceal it with some thing like slightly tire tube so it would not worsen.
