Department: PHYSICS

PHYS1131: FUNDAMENTAL PHYSICS B

Prerequisites

• A-Level Physics and A-Level or AS-Level Mathematics.

Corequisites

• Either Single Mathematics A (MATH1561) and Single Mathematics B (MATH1571) or Core Mathematics A (MATH1012) or Maths for Engineers and Scientists (MATH1551).

Excluded Combination of Modules

• Foundations of Physics 1 (PHYS1122), Fundamental Physics A (PHYS1111).

Aims

• The module introduces basic concepts in wave phenomena, electricity and magnetism, and quantum mechanics.
• It is a subset of the double module Foundations of Physics 1, excluding the courses on Newtonian mechanics, special relativity, phases of matter, optics, atomic, nuclear and particle physics.
• For this reason it is not sufficient for progression to Level 2 physics modules.
• The module provides students with practice in key mathematical techniques an in the informal discussion of scientific ideas within a small group.

Learning Outcomes

• Students will have knowledge of the physics of vibrations and waves in many different linear systems and of optical wave phenomena including light propagation, diffraction and interference.
• They will have a firm grounding in the classical aspects of electromagnetism, including the central ideas of electrostatics, magnetostatics and time variations.
• They will understand the fundamental importance of quantum mechanics to modern physics and will be able to perform simple quantum mechanical calculations.

• In addition to the acquisition of subject knowledge, students will have developed problem-solving skills requiring the application of mathematical techniques and the basic principles of physics.
• They will know how to produce a well-structured solution, with clearly-explained reasoning and appropriate presentation.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• Teaching will be lectures, supported by tutorials and mathematics skills workshops.
• The lectures will provide the means to give a concise, focused presentation of the subject matter of the module.
• The lecture material will be explicitly linked to the contents of a single recommended textbook for the module, thus making clear where students can begin their private study.
• When appropriate, the lectures will also be supported by the distribution of written material, or by information and relevant links on DUO.
• Students will be able to obtain further help in their studies by approaching their lecturers, either after lectures or at other mutually convenient times (the Department has a policy of encouraging such enquiries).
• The mathematics skills workshops will improve students' knowledge of key mathematical topics and techniques used in physics.
• Regular problem exercises will give students the chance to develop their theoretical understanding and problem-solving abilities.
• These problem exercises will form the basis for discussions in tutorial groups of typically six to eight students.
• The tutorials will also provide an informal environment for students to raise issues of interest or difficulty.
• Student performance will be summatively assessed through a written examination and problem exercises.
• The written examination provides the means for students to demonstrate their acquisition of subject knowledge and the development of their problem-solving skills.
• The problem exercises provide opportunities for feedback, for students to gauge their progress, and for staff to monitor progress throughout the duration of the module.
