Summary of Intended Learning Outcomes
At the end of the Experimental Physics unit you should:
1) have learned how to keep a lab notebook
2) be able to combine errors in individual measurements
3) be able to fit a straight line to experimental data using least-squares methods & hence obtain the gradient, y-axis intercept & their uncertainties
4) have learned how to write up your experimental work as a scientific report

At the end of this course of lectures you should:

5) be familiar with the gaseous, liquid & solid phases of matter.

6) appreciate the universality of the Maxwell-Boltzmann distribution for systems in thermal equilibrium

7) understand how quantities such as latent heat, critical temperature, surface tension, compressibility, elasticity & thermal expansion can be related to the parameters of the inter atomic/molecular potential

8) understand the zeroth & first laws of thermodynamics & the concepts of internal energy, heat & work

9) understand the concept of electric field, Gauss's Law, and potential associated with charges and perform calculations in simple gemoetries.

10) understand capacitance in simple geometries, effect of polar dielectrics and RC circuits.

11) understand the concept of magnetic fields and forces of moving charges and currents,

12)understrand the relation between current and magnetic field inclduing Bio-Savert and Ampere's Laws and perform calcualtions for simple geometries.

13) understand the concept of induction including Faraday and Lenz's Law and perform cauclations in simple geometries.

14) state Maxwell's Laws in inegral form and explain their relations to laws of electro-magnetism.

15) qualitatively describe the magnetic properties of materials and the physical basis behind them.


16) be familiar with the failures of classical physics & how they relate to the early motivation for quantum theory

17) be able to state and appreciate the consequences of the key paradigm-shifting notions of early quantum theory such as the deBroglie Hypothesis & the Heisenberg Uncertainty Principle

18) be able to discuss the early models of atomic structure & their relation to optical spectra

19) be able to write down the time-dependent & - independent Schrodinger wave eqn & state why the latter has the structure of an eigenvalue eqn

20) be able to apply formal wave mechanics (through the Schrodinger eqn) to a range of fundamental problems concerning scattering & bound states.
