#### Learning Outcomes

Subject-specific Knowledge:

- Having studied the module students will be familiar with the formal theory of quantum mechanics and have an ability to use the theory to solve standard problems for model systems
- They will have a quantum mechanical understanding of the basic properties of the hydrogen atom and be able to use quantum theory to calculate various aspects of physical behaviour
- They will be able to carry out simple quantum mechanical calculations using the variational method and time-independent perturbation theory
- They will be familiar with and able to manipulate and solve Maxwell's equations in a variety of standard situations
- They will have an understanding of how the electrical and magnetic properties of simple media can be represented, and an appreciation of the key concepts relating to the propagation and radiation of electromagnetic waves in free space and simple media.

Subject-specific Skills:

- In addition to the acquisition of subject knowledge, students will be able to apply the principles of physics to the solution of predictable and unpredictable problems
- They will know how to produce a well-structured solution, with clearly-explained reasoning and appropriate presentation

Key Skills:

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- Teaching will be by lectures and tutorial-style workshops
- The lectures provide the means to give concise, focused presentation of the subject matter of the module. The lecture material will be defined by, and explicitly linked to, the contents of the recommended textbooks for the module, thus making clear where students can begin private study. When appropriate, the lectures will also be supported by the distribution of written material, or by information and relevant links online
- Regular problem exercises and workshops will give students the chance to develop their theoretical understanding and problem solving skills
- Students will be able to obtain further help in their studies by approaching their lecturers, either after lectures or at other mutually convenient times
- Student performance will be summatively assessed through a written examination and an online test and formatively assessed through problem exercises and a progress test. The written examination and online test will provide the means for students to demonstrate the acquisition of subject knowledge and the development of their problem-solving skills. The problem exercises, progress test and workshops will provide opportunities for feedback, for students to gauge their progress and for staff to monitor progress throughout the duration of the module.
