4. Define and apply the following wave characteristics: period, frequency, velocity, wavelength, amplitude, and energy.
5. Apply the following relationships: T=1/f and v =f*wavelength.
6. Explain how standing waves are produced and correctly use the terms nodes and antinodes.
7. Explain the following wave behaviors, interference, beats, resonance, doppler effect and sonic booms.
