640-237 Astrophysics & Optics II

Physics 640-121 and 640-122 (or 640-141 and 640-142); mathematics: one of 620-121, 620-140, 620-141 or equivalent.

This subject provides an introduction to two major areas of modern physics. In astrophysics, the basic structure of stars, our galaxy and the universe will be discussed, and the most recent research questions will be introduced. In optics, the nature and propagation of light will be explored and illustrated with reference to applications in modern instruments, and the principles behind lasers will be introduced.

Students completing this subject will be able to:

• explain and describe the structure and evolution of stars, the structure of the Milky Way and other cosmic objects and discuss cosmological models;

• explain the geometric and wave theories of optics and their application to instrumentation;

• explain the operational principles of lasers and the unique properties of laser light;

• solve and analyse problems relevant to the above topics.

In addition students will enhance their ability to plan effective work schedules and manage their time to meet the deadlines for submission of assessable work and prepare for tests and examinations.

Tests totalling up to 2 hours and assignments totalling up to an equivalent of 3000 words during the semester (20%); a 3-hour written examination in the examination period (80%).
