Northern Lights Chemistry
- The Northern Lights arise from electrons in atoms releasing absorbed energy as light.
- Different atoms emit specific colors, creating a unique emission spectrum like a fingerprint.
Emission Spectra as Fingerprints
- Atoms absorb and release energy in specific packets, like photons, corresponding to different colors.
- This creates distinct emission spectra, acting as fingerprints for different gases like oxygen and nitrogen.
The Sun's Role in the Northern Lights
- The sun's charged particles, carried by Earth's magnetic field, collide with atmospheric atoms.
- This collision transfers energy, causing the electrons to emit light, creating the Northern Lights.
