| Charged particles
moving along the earth’s magnetic field lines are accelerated by these
strong voltage drops in the auroral acceleration region.
This allows the accelerated particles to be guided and travel down the earth’s magnetic field lines where they collide with atmospheric molecules and atoms. The amount of energy and the type of atom or molecule hit creates the auroral light seen in our atmospheric screen in the sky.. |
The
front of your television or computer monitor is coated with chemicals
called "phosphors". Phosphors glow when electrons hit
them because
of the energy with which they hit and the type of atoms present within
it.
A typical color screen contains red, green, and blue phosphor dots
