Brief description
Electromagnetism, Oscillations and Waves, which mark the pinnacle of Classical Physics, have broad applications in the modern and industrial world and also provide simple descriptors of many microscopic phenomena. This module is devoted to providing a basic understanding of the fundamental physics and to applying this to simple macroscopic and microscopic systems. These include the response of simple electronic circuits to alternating currents and the varied physical properties of dielectric, magnetic and optical materials. The course will include numerical exercises and students will cover individual and group work, writing, IT and other associated skills in conjunction with laboratory practical module and tutorials.
