Difficult to judge exact peak, and analogue dials are extremely sensitive. More precise equipment could be used, although this is expensive.

# data[].attributes.body
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.

# data[].attributes.body
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.

# data[].attributes.body
Main systematic error was due to the microphone not being at the centre of the node

# data[].attributes.body
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

# data[].attributes.body
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

# data[].attributes.body
Unable to make precise adjustments to frequency on signal generator
Microphone only roughly in the middle of or a third along the tube
Resolution of the ruler measuring the tube length is 1mm
