Format of the Exam

Dont forget Dr Hawley's web resources, including a concise narrative of the material, as well as additional test questions. Although the material in those notes is essentially identical to ours, he was using a different text so the order of the topics is slightly different (use your judgement to sort out what is relevant to our current exam). His main web page is here.


Physical Constants you do not need to remember

Speed of light, c = 3.0 x 105 km/s = 3.0 x 108 m/s. Planck's constant, h = 6.62 x 10-34 J s (Joules x seconds). Wein's constant, 2.9 x 106 nm K (nanometers x Kelvins). Stefan-Boltzmann constant, sigma = 5.67 x 10-8 J/m2.K4.s 1 parsec = 3.08 x 1016m.
