##### Semesters
 Semester 1 Credit Value: 10 Semester 2 Credit Value: 10 ECTS Credits: 10.0

#### Aims

To present the dynamics of simple and damped harmonic oscillators and to give examples of systems exhibiting this behaviour. To present the impact of a driving force on this motion and the phenomenon and description of resonance.

To present techniques needed for analysis DC and AC circuits. To impart an appreciation of the analogy between AC circuits analysis and mechanical oscillations.

To present an introduction to the subject of coupled oscillations, with an introduction to normal mode analysis.

To present an introduction to wave propagation and an introduction to the wave equation. To introduce phase and group velocities and the Doppler effect.

To present a study of the transmission and reflection of waves at interfaces.

To introduce concepts of states of matter with a focus on solid state materials to act as a foundation for later course.

To introduce phase diagrams and discuss phase transitions.

To give some understanding of some thermal properties of matter.

##### Teaching Rationale And Relationship

Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work.

#### Assessment Methods

The format of resits will be determined by the Board of Examiners

##### Assessment Rationale And Relationship

A substantial formal unseen examination is appropriate for the assessment of the material in this module. The coursework assignments allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; these assessments have a secondary formative purpose as well as their primary summative purpose.

In the event of on-campus examinations not being possible, an on-line alternative assessment will be used for written examination 1.
