Astronomy 10: concept list for 1st Exam, Chapters 1-8

Know definitions of units:
c=3x10^8 m/s

Know formulas:
Kepler's 3rd law
Newton's law of gravity
parallax distance
luminosity depending on radius and temperature

Be able to use (no need to memorize but know concepts/proportionality):
magnitude difference <-> ratio of luminosity
small-angle formula
energy of a photon
speed = wavelength * frequency
Wien's law
Stefan-Boltzman law
Doppler effect
