ASTR 1010 Fall 2007 Study Guide for Quiz #3

READING: Chapter 2, page 54-59; Chapter 3; Chapter 4; Chapter 5. Topics you should know and understand for Quiz #3 (not necessarily a complete list)

1) DEFINITIONS: weightlessness (freefall), kinetic energy, potential energy, radiative energy, joule, calorie, Calorie (kilocalorie), watt, kilowatt-hour, center of mass, escape velocity, light, electromagnetic radiation, thermal radiation (also called heat radiation or blackbody radiation), electromagnetic spectrum, wavelength, frequency, Hertz (Hz), megahertz (MHz), luminosity, emission line spectrum (bright line spectrum), absorption line spectrum (dark line spectrum), atom, proton, neutron, electron, energy level diagram, Doppler shift, redshift, blueshift, excitation, ionization, ion, isotope, deuterium (deuteron), refraction, reflection, chromatic aberration, concave mirror, convex mirror, focus, focal length.

2) LAWS OF NATURE: Wien's Law; the mathematical formula for calculating the center of mass; velocity of circular motion formula; escape velocity formula; Stefan's Law; Kirchoff's Laws; the relationship between the energy, the wavelength, and the frequency of light; the Law of Reflection.

3) OTHER THINGS YOU SHOULD KNOW: The six main regimes of the electromagnetic spectrum, and their relative wavelengths, energies, and frequencies; units of mass, distance, density, velocity, acceleration, energy, force, power (luminosity), temperature, and frequency; what weightlessness is; what causes a) a continuous spectrum, b) an emission line spectrum, and c) an absorption line spectrum; two processes that can excite (or ionize) an atom; the basic energy level diagram of the hydrogen atom, and what jumps produce the H-alpha and H-beta lines; the basic designs of telescopes (i.e,. refracting, Newtonian, Prime Focus, Cassegrain, or Coude).
