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

    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. 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 hydrogen as well …

  3. 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 atom.

  4. Atomic spectra (video) | Khan Academy

    And we will call this the atomic spectrum, or the hydrogen spectrum. And what's cool about the atomic spectrum is that every element will have its own energy level.

  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 state multiple …

  6. Bohr's model of hydrogen (article) | 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 hydrogen as well …

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

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

  8. Signal characteristics - shape (video) | Khan Academy

    Explore how hydrogen bonding impacts the IR spectrum in alcohols and carboxylic acids, causing the shape of an IR signal to become broader and less sharp. Learn how electronegativity and bond …

  9. Line Spectra (practice) | Atomic structure | Khan Academy

    In a classroom experiment, the hydrogen atoms are excited, and a student observes visible lines in the hydrogen emission spectrum when the highest energy state is n = 5 .

  10. 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 when the electron …
