📚 The hydrogen atom is the simplest and most abundant of all elements in the Universe. In this video, we discuss the emission spectrum of hydrogen, which is mathematically given by the Rydberg formula. The emission spectrum of hydrogen was discovered before the development of atomic theory, and it played a key role in the discovery of quantum mechanics. We discuss the origin of the spectral lines, and classify them into groups such as the Lyman or Balmer series. We also discuss the importance that the hydrogen emission spectrum has for our understanding of large-scale structures in the Universe, such as star forming nebulas, and take a look at a beautiful image of the Orion nebula by the Hubble Space Telescope.
