Undergraduate Course: Modern Physics (PHYS08045)
|School||School of Physics and Astronomy
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 8 (Year 2 Undergraduate)
||Availability||Available to all students
|Summary||This course is designed for pre-honours physics students continuing from PH1. It provides an introduction to special relativity and quantum physics. It serves both as a preparation for further study in physics-based degree programmes, and as a stand-alone course for students of other disciplines, including mathematics, chemistry, geosciences, computer science and engineering. The course consists of lectures to present new material, and workshops to develop understanding, familiarity and fluency.
Modern Physics (20 lectures)
* Special Relativity
- Definition of inertial reference frames and invariance of speed of light (postulates of SR). Michelson Morley experiment. Role of the observer.
- Time dilation and Lorentz contraction. Events. Synchronisation. Moving clocks. Synchronised clocks in one frame viewed from another moving frame.
- Doppler (red shift) and its implications, the Lorentz factor, addition of velocities. Twins paradox. Rod and Shed paradox.
- Geometric formulation of SR (Minkowski Diagrams), and their relation to time dilation, Lorentz contraction, order of events, relativistic Doppler, world lines
- Momentum and relation to mass and energy as a relativistic property.
*Introduction to Quantum Physics

On completion of this course, the student will be able to:
- State the basic principles of special relativity and elementary quantum mechanics, and the regimes in which the different theories apply.
- Apply these principles in conjunction with elementary mathematical techniques to solve simple problems.
- Present a solution to a physics problem in a clear and logical written form.
- Assess whether a solution to a given problem is physically reasonable.
- Locate and use additional sources of information (to include discussion with peers where appropriate) to facilitate independent problem-solving.
