Transcript

  • 1. RGB 3 images 502nm 656nm 673nm H-alpha SIIOIII
  • 2. Origin of the lines • These lines are the result of atoms jumping from one state to another • Different atoms have different spectral signatures • Observation of a line can tell us exactly what atom is responsible. • Dark lines are the result of atoms absorbing light, and bright lines are due to atoms emitting light.
