SCHOOL OF ENGINEERING – MODULE DESCRIPTION APHY 112 Electromagnetism and Optics with Lab Prerequisites: APHY111, AMAT122 (will be taken concurrently) Aims: Lectures 3 Labs 1 Project No To gain an understanding of the considerations of electromagnetism and optics. To provide an understanding that most engineering problems are related to electromagnetism and optics. To introduce the principles, of electromagnetism and the related laws. To study the law of reflection and refraction and their applications to optical instruments. Outcomes: By the end of this course students should: Be able to distinguish between static electricity and current Understand that electric and magnetic forces are intimately related Be able to solve circuits Be able to apply the laws of geometric optics Description: Physics Section ECTS 5 Charge and Matter: Introduction to electromagnetism, Electric charge, Coulomb's Law, Conductors and isolators.
