Document Summary

There were many failed attempts to detect stellar parallax, owing to the incorrect assumption that the brightest stars are the nearest stars. Incorrect assumption, as stars vary in brightness and size. What is the definition of a parsec? (note: the specific values in km aren"t necessary here). Light year=the distance light travels in one year. Huygens: all light sources contain charged particles that move around (creating electric fields: describe how a wave from a bright blue light source is different from a wave from a faint red light source. Wave from a bright blue light source: short wavelength & high frequency. Blue light has higher energy than red light (shorter waves=more energy) Wave from a faint red light source: long wavelength & low frequency. Wavelength determines the amount of energy the wave carries from its source. An apparatus for producing and recording spectra for examination. Fraunhofer passed sunlight through glass and observed the spectrum through a telescope (i. e. a.
