  1. Absorption spectrum (emission spectrum lines) (article ... - Khan …

    Learn why every element has a unique emission/absorption spectrum, and how we can use spectral lines to identify the composition of an object.

  2. Emission spectrum of hydrogen (video) | Khan Academy

    The Balmer Rydberg equation explains the line spectrum of hydrogen. A line spectrum is a series of lines that represent the different energy levels of the an atom. In this video, we'll use the …

  3. Spectroscopy: Interaction of light and matter (article) - Khan …

    How UV-Vis and IR radiation can be used to chemical structure and concentrations of solutions

  4. Absorption and emission (video) | Khan Academy

    We got this equation, and in the next video we're going to see how this explains the emissions spectrum of hydrogen. Think about lambda or the wavelength, right as the light is emitted …

  5. Spectroscopy: Interaction of light and matter - Khan Academy

    How come Hydrogen has multiple lines in its atomic emission spectrum if it only has one electron? Does that mean that that one electron jumped back and forth between grounded and excited …

  6. Atomic spectra (video) | Khan Academy

    If light passes through a gas, the gas absorbs specific wavelengths -> absorption lines (like hydrogen or helium). You still see hydrogen/helium lines from the Sun because its light passes …

  7. Emission spectrum of hydrogen (video) | Khan Academy

    So, here, I just wanted to show you that the emissions spectrum of hydrogen can be explained using the Balmer Rydberg equation which we derived using the Bohr model of the hydrogen …

  8. INTERACT: Absorption lines | Khan Academy

    INTERACT: Absorption lines | Khan Academy ... Khan Academy

  9. Bohr's model of hydrogen - Khan Academy

    Bohr was the first to recognize this by incorporating the idea of quantization into the electronic structure of the hydrogen atom, and he was able to thereby explain the emission spectra of …

  10. Atomic spectra (apply) (practice) | Khan Academy

    Apply your understanding of atomic spectra in this set of free practice questions.
