But he notes that the set - up might not work for the entire visible spectrum, because it would be difficult to prevent visible light with shorter wavelengths being absorbed or sent elsewhere, resulting in dark spots. (newscientist.com)
Conventional mirrors contain a silvery layer that reflects a broad range of light, including the entire visible spectrum. (sciencenews.org)
This reversible dehydration and rehydration, shrinking and swelling, changes the thickness and spacing, which, in turn, changes the wavelength of the light that's reflected, thus «tuning» the color change over the entire visible spectrum. (sciencedaily.com)
