Description

This module will develop the student's understanding of fundamental concepts and ideas in modern physics, specifically the use and application of the Schroedinger equation, and the priciples of special relativity.

Learning Outcomes

1. Define key concepts in modern physics including wave function, probability amplitude, reference frame, invariance.
2. Solve the Schroedinger equation for 1-dimensional potential wells.
3. Apply the 3-d Schroedinger equation to the hydrogen atom.
4. Apply the basic relationships of special relativity to high energy particles.
5. Derive, from given premises, relevant relationships between physical variables.
6. Solve problems, from information given, requiring the calculation of the values of physical variables in quantum mechanics and relativity.
7. Explain the relevance of quantum theory and relativity in modern views of the physical universe.
