Unit Information

Why is this unit important?

This unit will continue developing your core knowledge in Physics; in addition to building on areas we started in Year One (including quantum and thermodynamics) we will introduce new areas of relativistic physics and the phenomena around electromagnetism. This will serve to further develop your intuition as a physicist and enhance your awareness of the physical universe; interpreting, applying and developing mathematical models to gain deeper understanding of the world around us.

How does this unit fit into your programme of study?

This unit is the second step of developing your core knowledge of Physics. You will take the teaching from Y1 Introduction to Quantum physics, and develop this further to explain real-world phenomena; you will learn how to connect the thermodynamic principles in Y1 with the microscopic world of particles to better understand the fundamental nature of matter. Additionally you will learn about the fundamental relationship between electricity and magnetism which underpins much of our understanding of the interactions of light and matter.

Your learning on this unit

An Overview of Content

This unit will build on topics from your first year of study, while also introducing new areas of physics which are built on your increased understanding of physics from Year One.

  • Special Relativity, including:
    • A historical introduction, Einstein’s postulates and frames of reference
    • Length contraction, time dilation, concepts including causality, simultaneity and velocity transformation
    • Relativistic energy, kinematics, and using a four-vector approach with Lorentz transformation matrices
  • Electromagnetism, including:
    • Overview of electrostatics, charges, fields, forces, potential and dipoles
    • Magnetic fields, the Lorentz force law, and the magnetic field of currents.
    • Gauss’s, Ampere’s and Faraday’s Laws; Maxwell’s equations in free space and in matter
    • Optical phenomena of electromagnetic waves, reflection, refraction, diffraction and interference
  • Quantum Physics, including:
    • Extending the learning from Y1 to studying the mechanics of a particle moving in space. Introducing the wavefunction and operators for position, momentum and the Hamiltonian
    • The Schrödinger equation; solving using the method of separation of variables and application to a free particle.
    • Quantum mechanical models including the infinite square well, the quantum harmonic oscillator, dynamics of particles in wells.
  • Extension from motion in one dimension to motion in three dimensions.
  • Statistical Mechanics, including:
    • Principles of micro- vs macro-states, equilibrium, probability and statistical averages in thermodynamic systems
    • A deeper look at entropy and the second law, the Boltzmann distribution, partition functions and thermodynamic ensembles
    • Properties of gases, including equipartition, statistical mechanics of the ideal gas and weakly interacting systems
    • More complex systems; variable particle numbers, phase transitions, heat capacities and quantum gases.

How will students, personally, be different as a result of the unit

This unit will further strengthen your physics understanding; in year one we focussed on learning how to translate problems into the language of Physics and Mathematics; this unit will develop that intuition for you to act and communicate naturally as a physicist.

Learning outcomes

By the end of this unit, you should be able to:

  • Demonstrate knowledge and understanding of unit content through coursework and examination
  • Combine knowledge of pre-requisite units with knowledge of this unit to explain more complex physical phenomena
  • Create models and apply appropriate mathematics to describe and solve problems within the physics presented
  • Reflect on your own development as a physicist, recognising strengths and identifying opportunities for improvement using the feedback given to successfully solve new problems in the assessment

How you will learn

The unit is organised through our on-line learning environment (OLE). This is where you will find information about the unit, lecture notes, any pre-recorded videos, recordings of lectures and live sessions, and other learning resources.

Teaching activities will be delivered face-to-face (barring intervention from exceptional events), and it is an expectation that you engage with these activities. Learning activities will be split across in-class activities (lectures, problems classes) and those around your own private study (for example pre-recorded videos, textbook references etc.).

The unit will consist of around 60 hours of content delivery with 20 hours of problems support. Along with this time there is an expectation of personal study in line with the University statement on student workloads.

Some sessions may require preparation beforehand (e.g. watching a video, reading a textbook chapter or journal article or similar); where these materials are provided, you should aim to spend around one hour of preparation time for one hour of face-to-face teaching. This will allow you to make the most of class discussions and activities.

Problem classes will have emphasis on problem-based learning, where you will be able to discuss the problems with others in a group.

How you will be assessed

Tasks which help you learn and prepare you for summative tasks (formative):

You will have regular problems classes, allowing you to ask questions of the facilitator to help you quantify your own understanding and that of others, and to gain verbal feedback on your problem solving skills.

Tasks which count towards your unit mark (summative):

You will complete four pieces of assessed coursework, one covering each component of the unit. Each coursework will contribute 7.5% of the unit mark for a total contribution of 30%. (ILOs 1-4)

Examinations covering all learning objectives:

  • Winter examination on Special Relativity and Electricity and Magnetism (20%)
  • Summer examination on Statistical Mechanics and Quantum Physics, with synoptic questions across the whole unit (50%)

Assessment breakdown

  • Assessed coursework: 30% (4 x courseworks of 7.5%)
  • Mid-year examination: 20%
  • End of year examination: 50%

When assessment does not go to plan

If you do not pass the summer exam you may have the opportunity to take the exam in the next available assessment period.* The reassessment will take the form of a single examination covering all learning objectives and in a similar format to the Summer assessment, but covering all areas of the unit. You should contact the Senior Tutor if you think your assessment might not be going to plan, and you can discuss with your personal tutor for support. If you feel your examinations have been affected by any exceptional circumstances, you must contact the Senior Tutor before the advertised cut-off date.

  • subject to passing a minimum overall number of credits for the year

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. PHYS20040).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the University Workload statement relating to this unit for more information.

Assessment
The assessment methods listed in this unit specification are designed to enable students to demonstrate the named learning outcomes (LOs). Where a disability prevents a student from undertaking a specific method of assessment, schools will make reasonable adjustments to support a student to demonstrate the LO by an alternative method or with additional resources.

The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. For appropriate assessments, if you have self-certificated your absence, you will normally be required to complete it the next time it runs (for assessments at the end of TB1 and TB2 this is usually in the next re-assessment period).
The Board of Examiners will take into account any exceptional circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
