Unit 9 - Mechanical Waves and Sound

▼ 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?
