Wavelengths Quotes

“The addition of certain chemicals to the atmosphere will destroy wavelengths of light and it may only be a matter of time before one of these wavelengths of light that is critical for human survival is eliminated. This is called: The Extinction Wavelength”
― Steven Magee, Solar Radiation, Global Warming and Human Disease

“Although irises come in different colors (iris = rainbow), they contain only brown pigment. When they have a lot of pigment, the eyes appear brown or black. If the amount of pigment is small and restricted to the posterior surface of the iris, the unpigmented parts simply scatter the shorter wavelengths of light and the eyes appear blue, green, or gray. Most newborn babies’ eyes are slate gray or blue because their iris pigment is not yet developed.”
