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.
Here is a disco ball where my engineer/mathematician/computer scientist son François performed techno music in Montréal, QC, Canada, looked through a diffraction grating glass.
Here is a blank screen, looked through a diffraction grating glass.
Here is an object on a screen, split into 3 component colours (RGB).
Here is an image from incandescent/LED light source, split into 3 component colours (RGB).
Here is an image from monochromatic light source, not split into component colours.
