What about the general properties of chromaticity diagrams that are different from humans, discuss color mixing for bees. Perceived color depends only on relative stimulation of S, I, and L cones. In dim lights, however, rods take over and color constancy fails. Temporal processing . Happens when looking at white after adjusting to one color.
Coherent sources have the same wavelength and start with the same initial phase.
Iridescence in peacock feathers, Morpho butterfly wing, compact disc, etc. X-ray diffraction patterns for crystals. What are the parts of the usual interferometer. Huygen's principle Replace wavefront with many sources to find subsequent wavefronts. Diffraction Light spreads out or blurs going through a slit or any hole.
