More precise equipment could be used, although this is expensive.]]> 2022-10-11 10:49:24 UTC https://padlet.com/firstyearlabs/speedofsound/wish/2335048831 https://padlet.com/firstyearlabs/speedofsound/wish/2336748901 Systemic errors due to microphone’s mounting on ruler, improve using a sliding scale and vernier thingy. Also systematic errors due to atmospheric effects, so do in a controlled atmosphere if possible. Main random error is due to manipulating an analogue dial to measure frequency.]]> 2022-10-12 09:53:35 UTC https://padlet.com/firstyearlabs/speedofsound/wish/2336748901 https://padlet.com/firstyearlabs/speedofsound/wish/2336750697 Random error included the distance between the speaker and the tube. Systematic error would be the precision of the equipment. To improve, take more harmonic measurements and repeat to allow an average to be taken.]]> 2022-10-12 09:55:11 UTC https://padlet.com/firstyearlabs/speedofsound/wish/2336750697 https://padlet.com/firstyearlabs/speedofsound/wish/2336765044 Main systematic error was due to the microphone not being at the centre of the node ]]> 2022-10-12 10:08:51 UTC https://padlet.com/firstyearlabs/speedofsound/wish/2336765044 https://padlet.com/firstyearlabs/speedofsound/wish/2336782243 2022-10-12 10:25:22 UTC https://padlet.com/firstyearlabs/speedofsound/wish/2336782243 https://padlet.com/firstyearlabs/speedofsound/wish/2336798520 Systematic error due to the speaker not being exactly on the tube as well as the microphones mounting not being exact, speaker issue could be improved by mounting it to the tube rather than to the magnet, random error from using the dial on the generator as it had a very high sensitivity]]> 2022-10-12 10:39:57 UTC https://padlet.com/firstyearlabs/speedofsound/wish/2336798520 https://padlet.com/firstyearlabs/speedofsound/wish/2338477355 2022-10-13 09:52:48 UTC https://padlet.com/firstyearlabs/speedofsound/wish/2338477355 https://padlet.com/firstyearlabs/speedofsound/wish/2338484095 Random errors: difficulty in holding the mic stable, increasing the frequency in small increments and estimating where the peak was as it wasn't clear and there was some noise
Systematic errors: the speaker may not have been close enough to the tube and/or in line]]> 2022-10-13 09:58:30 UTC https://padlet.com/firstyearlabs/speedofsound/wish/2338484095 https://padlet.com/firstyearlabs/speedofsound/wish/2338487330 Unable to make precise adjustments to frequency on signal generator
