Semester 2 Unit 1 Waves and Sound

Goals:

1. Explain what a wave is.
2. Differentiate between longitudinal and transverse waves.
3. Correctly use the vocabulary: medium, pulse, crest, trough, compression, and rarefaction.
4. Define and apply the following wave characteristics: period, frequency, velocity, wavelength, amplitude, energy
5. Apply the following: 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.
