Chapters 1-6 in your text (Seeds Horizons: Exploring the Universe) corresponding to Lessons 1-7 (videotape series) - see review for each exam from orientation materials and Study Guide for video telecourse. The videos supplement the material presented in the text.

Things to note -

1. words in bold type
2. Summary and New Terms at the end of each chapter
3. Review questions at the end of each chapter
4. Problems

Chapter 1 - The Scale of the Cosmos

1. scientific notation
2. scale comparisons - see also 'time scale' comparison in handout from orientation

1. magnitudes (apparent & absolute) - see section 8-2 for relationship between magnitudes & distance in parsecs
2. Angles in the Sky section + sheet on Celestial Sphere definitions (some of this is also in Ch 3)
3. Precession - know cause
4. Be able to relate Right Ascension, Local Sidereal Time, and Hour Angle. Example: If the vernal equinox is on the eastern horizon and a star has a Right Ascension of 6 h, where is the star?

1. Know material on motion of the Moon and Sun
2. Phases of the Moon - when does each rise and set
3. Eclipses of Sun & Moon - Why and when do these occur? Why not each month?
4. Tides

1. Know about each person and what he did + people on history summary sheet in orientation materials
2. Geocentric vs. Heliocentric views of Universe
3. Kepler's laws - be able to apply (+ extension of 3^rd Law by Newton:  M₁+ M₂  = a³/p²  Note that the addl constants are not necessary if a is in AU's, p is in years, and M₁ and M₂ are in Solar Masses)
4. Newton's laws of motion + universal law of gravitation - be able to use

1. Plank's Law (E = hf) and l = c/f  (where c is the speed of light = 3 x 10⁸ m/s, f is the frequency, and l is the wavelength in meters)
2. See especially sec 5-1 - compare with sin q = 1.22 l/d where l is the wavelength of observations in meters, d is the diameter of the objective or mirror in meters, and q is the angle of resolution

1. Understand relationship between absorption/emission of a photon of light and state of electron
2. Know how to use formulae in sec 6-1: Wien's Law and Stefan-Boltzmann Law - be able to compare luminosity of stars of different temperatures
3. Understand Kirchhoff's laws and spectrum of hydrogen (various series, esp. Balmer)
4. Stellar Spectral Classes - know Spectral classes, approximate temperature, prominent spectral features (see table 6-1 and Figure 6-16) You will need these also on the next test - also find section on 'LUMINOSITY CLASSES' which appears later in your text.
5. Doppler Effect - how to use to determine radial velocity
