Module overview

This module covers introductory concepts of simple harmonic motion and waves, drawing on and bringing together examples from different branches of physics including mechanics, optics, electronics, and electromagnetism. It combines the mathematical description, physical interpretation as well as experiments and their analysis of oscillations and wave phenomena to provide a well-balanced introduction to the important physical concepts that are required for further study in subsequent modules of a physics course.

Module aims

provide a solid base for the important concepts that re-occur in (almost) all areas of physics relating to harmonic oscillations and wave phenomena.

introduce the general mathematical description as well as to the common physical interpretation and consequences concerning speed, frequency, energy, velocities etc. 

applied and re-inforce concepts through many examples of oscillations and waves

develop confidence and familiarity in students with the theoretical description and analysis of harmonic oscillations and waves  as well as performing experiments of wave related phenomena, for example in the area of mechanical springs, diffraction, standing mechanical waves, AC circuits etc.

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Describe what the module learning and teaching strategy is designed to achieve and how it relates to the programme learning and teaching strategy

The learning and teaching methods include:


33h of lectures, discussions, example classes and demonstrations as 3h/week x 11 weeks
20h of laboratory classes arranged as 5 half-day experiments


 

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

• during the laboratory components, tutorials and exam, that they have acquired a basic understanding and familiarity with waves in different context of Physics and that they can apply that knowledge in order to perform calculations predict experimental findings relating to wave phenomena.

Thus, the summative assessment for this module consists of:

• a written examination of 2h duration (week 13 or 14) with a section of short compulsory questions, and a section of longer questions with a choice of 2 out of 3.

• Laboratory diary entries (on selected experiments)

 

Formative assessment and feedback

Students receive formative verbal feedback during laboratory session from Academics and Demonstrators.

They also have the opportunity to receive feedback on their ability to apply the topics covered during the oscillations and wave lectures through:

- Small group tutorial sessions

- Exercise sheets and model solutions made available through the Virtual Learning Environment

- Multiple Choice revision questions during the lecture sessions
