 **Oscillation** - A repetitive variation (usually in time) for a measure or value about a central value, e.g. a sine wave oscillates regularly between two peak values (positive/negative) about a central value of zero. **Oscillation** - A repetitive variation (usually in time) for a measure or value about a central value, e.g. a sine wave oscillates regularly between two peak values (positive/negative) about a central value of zero.

 **Polarisation** - The property of a wave (usually transverse) that defines the geometrical orientation of the oscillation of that wave, e.g. a sine wave could be said to have vertical polarisation. **Polarisation** - The property of a wave (usually transverse) that defines the geometrical orientation of the oscillation of that wave, e.g. a sine wave could be said to have vertical polarisation.

 **Voltage** - A measure of the energy possessed by a quantity of electricity: a source of energy of one volt is able to deliver one joule of energy for each coulomb of charge that flows. It is measured in volts, V. **Voltage** - A measure of the energy possessed by a quantity of electricity: a source of energy of one volt is able to deliver one joule of energy for each coulomb of charge that flows.
