1/ Use the principle of superposition and the boundary conditions for a stretched string with a fixed or free end to explain the form of reflected pulses.
2/ Describe standing waves on a stretched string, recognising nodes and antinodes, and the relation to superposition of two travelling waves.
3/ Explain and use the mathematical expression for a standing wave.
4/ Describe the basis for production of normal vibration modes of a stretched string or an air column.
5/ Explain the terms fundamental, harmonics, overtones.
