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.
