Undergraduate Course: Physics 1B: The Stuff of the Universe (PHYS08017)
|School||School of Physics and Astronomy
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 8 (Year 1 Undergraduate)
||Availability||Available to all students
|Summary||This is an introductory-level course, giving an overview of a range of topics, including thermal physics, waves, elementary quantum mechanics, properties of matter, nuclear and particle physics, and astrophysics. The course is designed for those with qualifications in physics and mathematics at SCE Higher level or equivalent. It serves both as a preparation for further study in physics-based degree courses, and as a stand-alone course for students of other disciplines, including (but not limited to) mathematics, chemistry, computer science and engineering. The course includes an experimental laboratory element, Experimental Physics 1.
