Course Outline

The theory of electromagnetism was one of the great accomplishments of 19th century physics and, built on the general framework of Newton's Laws of mechanics, unified and explained a large range of phenomena associated with charged objects, currents and magnets. By the end of the century the theory had evolved to a compact and aesthetically pleasing form, which is still widely used.

Electromagnetism is arguably the most important way of probing and learning about the physical world. Almost all modern scientific laboratories and the experiments conducted in them would be impossible to imagine without extensive use of electronic equipment. Much of what is learned in these circumstances hinges on understanding the electromagnetic interaction between the equipment and the physical system that is being observed. Electromagnetism has made possible much of the technology that is characteristic of the industrialized world: electric appliances, electronics, electric motors, power generation, computers, wireless communication, etc,...

One of the predictions of the theory of electromagnetism is the existence of electromagnetic waves, which offer a complete description of the classical properties of light. Optics is the study of the properties of light. Some, such as reflection, refraction and image production using lenses are readily apparent. However, optics has consistently yielded surprising phenomena, which often provide fundamental insights into the nature of the physical world.

Phys 132 aims to introduce you to the phenomena of electricity and magnetism and optics and the theories which describe them as well as some of their practical applications.

The course will cover the following topics subject to minor modifications.

  1. Electric charge, fields, potentials and currents.
  2. Electric circuits.
  3. Magnetic fields, interaction with currents.
  4. Maxwell's equations, electromagnetic waves.
  5. Wave optics.
  6. Geometric optics.

Course Structure

The Monday, Tuesday and Thursday class meetings will usually be in lecture format. You will be expected to study the relevant sections of the text before class meetings.

Most Wednesday meetings will consist of a discussion/problem session during which you will work in small groups (with the instructor's help) on pre-assigned problems. You will be expected to attempt these before the Wednesday class meeting. There will be a short quiz covering the material at the end of the discussion session.
