Document Summary

700 nm (red) short wavelength, higher frequency long wavelength, lower frequency: yerkes observatory: largest refracting telescope in the world, vla- looks at radio waves. Radiation is radiation coal, what emitted by the yellow to blue changes continuous (all colors are emitted) the wavelength where the emission is more intense relates to the color of the star. Flux: the total amount of radiation given off by a square meter of an object in a second. Each molecule has kinetic energy: ke- motion, faster they move, higher the ke. Temperature: the average ke of particles: unit: kelvin. Heat: total energy of the particles: kelvin. Starts at 0 (absolute zero), all motion would stop, 0 ke. Sun: density decreases as you move out, photosphere: high temperature, very dense, corona: lower in density, molecules farther apart and moving faster. Lower density than photosphere and chromosphere: granulation. Photosphere of the sun is not uniform. Granule: bright area, 1000 km in size.
