Hydrogen alpha is a specific wavelength of visible light at 656.281 nm. A hydrogen atom emits a photon at this specific wavelength when its electron jumps from an excited quantum state or electron shell or energy level of n=3 to a lower level of n=2. Explore what H-alpha is, and how it is applied in astronomy.
Explore how Sun powers itself and find out how solar flare works. Also, find out the difference between a solar flare and a Coronal Mass Ejection event.
Explore the sun’s core and learn why the sun never fuses all the hydrogen at once. Also, find out how it balances the rate of fusion of the hydrogen ions when the rate of fusion changes.
