Knowledge and understanding of electromagnetic and relativistic laws and principles, and their application to diverse areas of physics. An ability to identify relevant principles and laws when dealing with problems in electromagnetism and relativity, and to make approximations necessary to obtain solutions.
An ability to solve problems in electromagnetism and relativity using appropriate mathematical tools.
An ability to use mathematical techniques and analysis to model physical behaviour in electromagnetism and relativity.
An ability to present and interpret information graphically.
An ability to make use of appropriate texts, research-based materials or other learning resources as part of managing their own learning.
Problem-solving skills, in the context of both problems with well-defined solutions and open-ended problems; an ability to formulate problems in precise terms and to identify key issues, and the confidence to try different approaches in order to make progress on challenging problems. Numeracy is subsumed within this area.
Analytical skills – associated with the need to pay attention to detail and to develop an ability to manipulate precise and intricate ideas, to construct logical arguments and to use technical language correctly.
