Learning & Teaching Activities
Learning & Teaching Modes
This course will be delivered by the following means:
- Lectures 30 x 50-minute sessions with up to three sessions per week
- Tutorials 11 x 50-minute sessions with one session per week
- Practicals 6 x 4-hour sessions with one session per week for 6 weeks
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.
A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).
Learning Activities Summary
The course content will include the following:
- Geometric Optics (14 lectures)
- Ray tracing, ABCD transfer matrices and Cardinal points in paraxial optical systems
- Aberration theory and wave-front distortion in optical systems
- Interference, Michelson, Mach-Zehnder and Fabry-Perot interferometers. , thin-film interference, multilayer dielectric coatings, antireflection coatings
- Polarization, Jones vectors and Jones matrices
- Condensed Matter (16 lectures)
- Crystal Structure; lattices, cubic crystal structure.
- Atomic vibrations in crystals, phonons, transport properties.
- Free-electron theory of metals.
- Nearly-free-electron model of semiconductors; energy band structure and band-gaps; metals, semiconductors and insulators; direct and indirect band-gaps.
- Doped semiconductors, abrupt PN junctions, PN diodes.
- Practical work (6 sessions)
Experiments carried out in groups of two students, selected from
- Cardinal points of a lens system
- Polarization of light
- Curie temperature
- Thermal diffusivity of copper
- Exponential decay and luminescence in solids
- X-ray diffraction
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment task Type of assessment Percentage of total assessment for grading purposes Hurdle (Yes/No) Outcomes being assessed Practical work Formative & Summative 18% No 6 – 10 Tutorial preparation Formative & Summative min 5% - max 10% No 1 – 5, 10 Tests Formative & Summative min 5% - max 13% No 1 – 5, 10 Final exam Summative min 59% - max 72% Yes (40%) 1 – 5, 10
Assessment Related Requirements
To obtain a grade of Pass or better in this course, a student must maintain a suitable logbook for at least 5 practical sessions during the semester, attend the examination and achieve at least 40% in the final exam.
2 x 50 minute, closed book tests taken during the semester, which have a formative and summative role and address essential aspects of the learning objectives for Optics and Condensed Matter Physics. The combined mark for both tests can contribute up to 13% to the final assessment; poor performance may be partly redeemed by superior performance in the final exam.
To maximise the benefit of tutorials, students are required to submit their answers before or at the tutorial. Assessment is based on effort rather than correctness; this task has a formative and summative role. It can contribute up to 10% to the final assessment; poor performance may be partly redeemed by superior performance in the final exam.
This summative assessment activity comprehensively addresses learning objectives 1 – 10.
Practical work (Practical achievement and practical reports)
Students work on an experiment until it is completed and they have an adequate report in their log book. Demonstrators provide formative assessment as the students are doing each experiment. Each student then selects one completed experiment and writes an extended lab report. The log book and report are assessed summatively. An opportunity to make-up a maximum of one missed practical session may be offered at the end of the semester.
Submission of Assigned Work
Coversheets must be completed and attached to all submitted work. Coversheets can be obtained from the School Office (room G33 Physics) or from MyUNI. Work should be submitted via the assignment drop box at the School Office.
Extensions for Assessment Tasks
Extensions of deadlines for assessment tasks may be allowed for reasonable causes. Such situations would include compassionate and medical grounds of the severity that would justify the awarding of a replacement examination. Evidence for the grounds must be provided when an extension is requested. Students are required to apply for an extension to the Course Coordinator before the assessment task is due. Extensions will not be provided on the grounds of poor prioritising of time.
Late submission of assessments
If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days or more late without an approved extension can only receive a maximum of 50% of the mark.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
