- An introductory overview to the application of these concepts in engineering practice.

Learning Outcomes:

1. Knowledge & Understanding
By the end of the study-unit the student will be able to:

- Explain wave propagation, reflection and diffusion;
- Describe the working principles of common engineering instruments working on the concept of wave theory;
- Describe and relate quantum theory to common engineering material characterisation applications;
- Explain how nuclear energy can be used in common engineering applications.

2. Skills
By the end of the study-unit the student will be able to:

- Apply wave theory to solve simple engineering problems (such as sound, signal transmission, etc);
- Identify systems utilizing nuclear science concepts for power generation, medical equipment and medicine, food industry, etc.
