resonance in closed air column
we have conduct a lab to determine the speed of sound and estimate room temprature by using open air column method. put a tube in the water, have a tuning folks (sound source) on the above, and pull the tube up and down to find the resonance length, then use the equation to find wavelength, then speed, and use another equation to find temprature.
so my question is watz the possible source of error in this lab.
\nu = (2n-1)v/4L or \nu =nv/2L
v=fh
v=331+0.59Tc
water meniscus and extra length of resonance length maybe two of them.
can anyone help me, please
