Outline

Overview

The development of electrodynamic field theory laid the foundation on which all of modern physics is built, from relativity to quantum field theory. Its application to electromagnetic waves and optics underpins all of modern telecommunications, but also some of the most delicate physics experiments, from gravitational wave detection to quantum computing. This is a core unit in the physics major, which has three components: electrodynamics lectures, optics lectures, and experimental lab. In electrodynamics you will learn to manipulate Maxwell's equations in their differential form. You will apply the formalism to deriving properties of electromagnetic waves, including the interaction of waves with matter through reflection and absorption. This will lead to optics lectures in which you will investigate aspects of modern optics, using the laser to illustrate the topics covered, in combination with a discussion of the basic optical properties of materials, including the Lorentz model. You will investigate spontaneous and stimulated emission of light, laser rate equations, diffraction, Gaussian beam propagation, anisotropic media and nonlinear optics. You will carry out in-depth experimental investigations into key aspects of electrodynamics, optics, as well as other topics in physics, with expert tutoring.

Assessment summary

Supervised quizzes: Each quiz may contain multiple choice and/or short answer questions. There are four quizzes in total. The best three marks count towards the final mark. Quizzes will take place in week 3, 6, 9, and 12, in person, on Friday at 11am. Presence is required.
Experimental physics lab books: Every student will carry out their allocated experiments during the semester, and produce a experimental logbook during the laboratory sessions that will be assessed by the tutors. This is a “hurdle task”. Must be attempted & must meet hurdle mark threshold otherwise = AF grade.
Experimental physics oral presentation: Students will give a 10 minutes technical presentation based on the material covered in their logbook. This is a “hurdle task”. Must be attempted & must meet hurdle mark threshold otherwise = AF grade.
Final exam: The final exam will be in person, paper based, and have questions covering all coursework aspects of this course.

Detailed information for each assessment can be found on Canvas.

Final exam: If a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam). The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name	Mark range	Description
High distinction	85 - 100	At HD level, a student demonstrates a flair for the subject and comprehensive knowledge and understanding of the unit material. A ‘High Distinction’ reflects exceptional achievement and is awarded to a student who demonstrates the ability to apply subject knowledge to novel situations.
Distinction	75 - 84	At DI level, a student demonstrates an aptitude for the subject and a solid knowledge and understanding of the unit material. A ‘Distinction’ reflects excellent achievement and is awarded to a student who demonstrates an ability to apply the key ideas of the subject.
Credit	65 - 74	At CR level, a student demonstrates a good command and knowledge of the unit material. A ‘Credit’ reflects solid achievement and is awarded to a student who has a broad understanding of the unit material but has not fully developed the ability to apply the key ideas of the subject.
Pass	50 - 64	At PS level, a student demonstrates proficiency in the unit material. A ‘Pass’ reflects satisfactory achievement and is awarded to a student who has threshold knowledge of the subject.

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Learning support

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.
