Created with Fabric.js 1.4.5 Blue & Black? White & Gold? Problem Explanation Thin Film Interference Background Lorem Other Species Diagram Bonquisha was walking throughthe tropical rainforest when she stumbled upon a blue morphobutterfly. She grabbed her friend, Ashley, who remarked, "what a beautiful white and goldbutterfly!" Outraged, Bonquisha demanded that she observe the blue iridescent shimmer. HelpBonquisha prove to Ashley the true color of the butterfly by using the minimum thickness of 64 nm and the index of refractionof 1.5. G: m=0, n=1.5, d=64 nmU: wavelength=?E: 2d=(m+1/2) wavelength/nS: 4dn=wavelengthS: 4(1.5)(64nm)384 nm -> BLUE! When a wave reaches theboundary between two media, a portion of the wave reflects off the boundary and a portion is transmitted across the boundary. The reflected portion of the wave remains in the original medium. -They use light interacting structures to produce color to their wings-nano-sized transparent chitin and air layered structures (What the wings are composed of)-selectively cancel out certain colors through wavelength interference while reflecting others-microstructures, rather than pigments, are the reason for the coloration of the wings of the butterfly The BlueMorphoButterfly ->It is one of over 29 species and 147 subspecies of butterfly in the group Morpho->Wingspan is more than 15 cm ->Structures on the scales of the wing are tree-like in shape and are arranged in rows. The rows of these structures, act as a diffraction grating which in part causes the blue color. ->Color of their wings is blue regardless of the viewing angle due to pigment beneath each of their scales, which is brown. - absorbs the unnecessary green to red light, which reduces the background reflection and enhances the blue structural color SOURCES:"The Giant Blue Morpho Butterfly (Morpho Didius)."
