### 20 creditsClass Size: 30

Module manager: Dr Alison Voice
Email: A.M.Voice@leeds.ac.uk

Taught: Semester 2 (Jan to Jun) View Timetable

Year running 2023/24

### Pre-requisite qualifications

A level Physics and Maths or equivalent

### This module is mutually exclusive with

 PHYS1210 Physics 2- Properties of Matter PHYS1250 Vibrations and Waves (Geophysics)

This module is not approved as a discovery module

### Module summary

Vibrations and waves are ubiquitous phenomena, occurring in widely different physical systems, from molecules to musical instruments to tectonic plates. Nevertheless, they can be described by a common mathematical approach.Thermodynamics is a fundamental branch of physics with applications as diverse as astrophysics, condensed matter, biophysics and climate change. The module will cover macroscopic effects of heat flow which can be explained by behaviour at the molecular level.

### Objectives

Learning outcomes
Students will be able to demonstrate knowledge, understanding and application of the following:
In Vibrations and Waves
1. Damped and Driven harmonic oscillators
2. Travelling waves, impedance and sound
3. Diffraction and Interference (including Fourier Transforms)
4. Laws of Reflection and Refraction (Geometrical optics)

In Thermodynamics:
1. Heat transfer mechanisms
2. Ideal gas behaviour, P,V,T
3. Real gases and simple phase diagrams
4. 1st law and 2nd law

Skills outcomes
Understanding, explanation, derivation and problem solving in vibrations, waves, and thermodynamics.
