In this activity, museum visitors will be exposed to the term ‘Photonic Crystals’. They will see and explore some of the well-known photonic crystals in nature and will also be able observe one method that scientists use in trying to replicate this process.
This illustration shows a butterfly's wing across ten orders of magnitude, from the butterfly to the atoms of which it is made. Using the conventions of visual perspective the image travels in one continuous “landscape” from the human scale at the top to the atomic scale in the foreground. Placing objects from the butterfly's wing in one frame clarifies connections between components, highlighting the system’s reliance on structures at very different scales.
The colors of the Blue Morpho's wing are generated by nanometer-sized structures on the wing's scales. In this image, light reflected from the scales creates the Morpho's characteristic iridescent blue color.
The colors of the Blue Morpho's wing are generated by nanometer-sized structures on the wing's scales. In this image, only the light passing through the wing is seen, revealing the wing's pigment-produced brown hue.
