Potential Discovery or Invention
Diffraction grating is an optical grating with a periodic structure that diffracts light, or another type of electromagnetic radiation, into several beams traveling in different directions (i.e., different diffraction angles). The emerging coloration is a form of structural coloration. A diffraction grating can create "rainbow" colours when it is illuminated by a wide-spectrum (e.g., continuous) light source.
Plasma globe is a clear glass container filled with noble gases, usually a mixture of neon (Ne), krypton (Kr), and xenon (Xe), that has a high-voltage electrode in the centre of the container. When voltage is applied, a plasma is formed within the container. Plasma filaments extend from the inner electrode to the outer glass insulator, giving the appearance of multiple constant beams of coloured light.
