Q

what are the 2 problems with the experiment where two people stand a distance apart where one has tambarines and other has a timer to test the speed of sound?

A
  1. everyone has different reaction times. for example they will start timer a fraction of time later then when they clapped. to fix this they should have more than 1 observer, collect results then discard any anamolous, then calculate mean
  2. there is a very short difference in between hitting the tambarines and hearing the sound so hard to get it accurate as it is fast. to fix this make the distance between 2 people bigger so more time for reaction.
