Sources of error for speed of sound lab

Click For Summary
SUMMARY

The discussion focuses on identifying sources of error in a physics lab experiment measuring the speed of sound using wooden sticks and a stopwatch. Key errors include the reaction time of the individual operating the stopwatch, which is the most significant factor affecting accuracy. Other potential errors, such as environmental conditions like rain, are considered less impactful. The experiment involved distances of 100 m, 200 m, 300 m, and 400 m from a wall to measure echoes.

PREREQUISITES
  • Understanding of basic physics concepts related to sound waves
  • Familiarity with experimental design and measurement techniques
  • Knowledge of human reaction time and its impact on timing accuracy
  • Experience with using stopwatches for time measurement
NEXT STEPS
  • Research methods to minimize human error in timing experiments
  • Explore the effects of environmental conditions on sound propagation
  • Learn about advanced timing techniques, such as electronic timers
  • Investigate the physics of sound waves and their behavior in different mediums
USEFUL FOR

Physics students, educators conducting lab experiments, and anyone interested in improving accuracy in sound measurement experiments.

Hi!
Last Week we did a Physics lab on Speed of Sound. Two wooden sticks were banged against each other at a distance of 100 m from the wall(Then we went to 200 m, 300m and finally 400m) and the echo was heard and time was measured using a stopwatch. It was a rainy day. Can anybody suggest me some sources of error for that lab? Thank you!

The largest source of error would definitely be the reaction time of the person in charge of the stopwatch. compared to this I would think that all the other errors are negligible.
