  • Atomic Spectra

    Example: Hydrogen Atom Spectrum

    When an electron in a hydrogen atom absorbs energy, it moves to a higher energy level (excited state). When it falls back to a lower energy level, it emits light at specific wavelengths. These wavelengths form discrete lines in the atomic spectrum of hydrogen, known as the Balmer series in the visible range. This emission spectrum is a result of the quantized energy levels of electrons and provides key evidence for the Bohr model of the atom.
