# OSCILLATIONS AND WAVES - 2023/4

Module code: PHY1036

## 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.

## Assessment pattern

Assessment type Unit of assessment Weighting
Pass/Fail competencies EDI Awareness Engagement Pass/Fail
Practical based assessment Laboratory Diaries 20
Coursework Bi-weekly Small Group Tutorial Session Questions 10
Examination End of Semester Examination - 2 hours 70

## Alternative Assessment

Assessed Laboratory experiments with associated report may replace the laboratory Unit of Assessment. Bi-weekly Small Group Tutorial questions may be replaced with an alternative question set

## 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:

• Laboratory diary entries (on selected experiments). These diary entries will not be marked anonymous, in order to allow follow up with students in the subsequent lab sessions, as well as cross checking diary entries with attendance. The average mark of the Laboratory entries needs to be above 40 % in order to pass the module.

• Bi-weekly hand-in questions from Small Group Tutorial Sessions.

• A written examination of 2-hour duration with a section of short compulsory questions, and a section of longer questions with a choice of 2 out of 3.

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 Waves lectures through:

- Small group tutorial sessions

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

- Multiple Choice revision questions during the lecture sessions

EDI Training

The assessment of engagement with the EDI Awareness Workshop will be by an open book quiz with unlimited re-attempts, but it must be passed in order to pass the module.

## 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:

• lectures + tutorial sessions

• laboratory classes (shared with PHY1035) which are supported by guided learning

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
