Module summaryVibrations and waves are ubiquitous phenomena in the world. In spite of occurring in widely different physical systems, they can be described by a common mathematical approach.In the course, we study simple and damped harmonic motion, the characteristics of waves, such as their superposition, interference and diffraction in light and sound, and geometrical optics, namely refraction, reflection, lenses and optical instruments.
ObjectivesAt the end of this module you should be able to:
- describe harmonic vibrations using mathematical formulae;
- calculate the properties of vibrating systems;
- describe the properties of waves and predict their motion;
- derive and utilise the wave equation;
- derive and utilise the laws of reflection and refraction;
- perform simple calculations on basic optical instruments;
- describe and differentiate between diffraction and interference of light.
