These glasses offer a new perspective of the world and show us some of the remarkable properties of light. Diffraction occurs when light passes through a narrow slit or a series of slits, called a grating, and is separated into its spectral components. The spectral components have different wavelengths and, thus, leave the gratings at different angles, resulting in a spectrum of light. For white light, one would see the colors of the rainbow, red, orange, yellow, green, blue, indigo and violet. You can experiment with other light sources and temperatures of light to see different spectrums!
WARNING: Do not stare into the Sun! Doing so could cause immediate and irreversible eye damage. These glasses do not offer protection from the Sun’s harmful ultraviolet rays.
