- MEASURING THE SPEED OF SOUND
Guiding Questions:
You should work towards understanding the following by the end of this unit.
- How is simple harmonic motion connected to uniform circular motion?
- How can oscillatory motion be represented graphically and mathematically?
- How is conservation of energy applied in simple harmonic oscillators?
- How are waves energy transport phenomena?
- How do the relative velocities of the source of a wave and of the observer affect the frequency of the observed wave?
- How do waves from more than one source interfere to make waves of smaller or larger amplitude, depending on the location where the waves meet?
- How can wave boundary behavior be used to derive and apply relationships for calculating the characteristic frequencies for standing waves in strings, open pipes, and closed pipes?
Today:
S.O.S.Given: Tuning forks of known frequency, a graduated cylinder of water, a PVC pipe which is slightly longer than the graduated cylinder.
Find: The speed of sound in air.
