I have carried out an experiment, placing tuning forks of different frequencies above a pipe in a cylinder of water to form a closed end pipe, and then recording the lengths at which resonance occurs, to find out fundamental frequecnies.
I have calculated the average speed of sound from these collected results, and compared it to the actual value of the speed of sound to work out percentage, and need to find ways of improving the experiment.
The Attempt at a Solution
One of the errors is due to me not including end correction. Another source of error is human judgement, but I don't understand how I could improve this experiment to reduce human judgment. Also, apart from human error and random error, are there any other sources of error I have not considered/?
Thanks for any help/
