Our eyes are sensitive to a particular wavelength range situated between 400 and approximately 800 nm corresponding to the visible light. The range of wave lengths associated with these colors form what we call the visible spectrum, or simply visible light. It is necessary that you understand that the colors are produced by the interaction of visible light with the objects that absorb some of the wavelengths and reflect others. Thus, we see the "things" because they reflect some of the light which is perceived by our eyes. A drop of blood is seen by us as red because when illuminated by white light reflects red light and absorbs almost all other visible spectrum. If a reflection proportion of all colors that make up the visible spectrum, we white, in the case of a full absorption black. The bald eagle (Haliaeetus leucocephalus) is native to North America. Bird of prey family Accipitridae, usually large, carnivorous, high visual acuity. Nevertheless, it was hunted almost to extinction. Is currently protected and recovery. This eagle has brown plumage, except the head which is typically white. Source: Bald Eagle at Combe Martin Wildlife and Dinosaur Park, situated in North Devon, England. Www.dinosaur-uk As we have said, the colors are produced by different wavelengths of visible light. But it should be noted that in nature there are numerous wavelengths that our eyes do not realize, eg: microwaves, radio waves, X-rays, ultraviolet rays or infrared rays. Moreover, animals are sighted wavelengths outside that range. The eagle can see part of the infrared and ultraviolet rays bees sighted. Representation of the electromagnetic spectrum.

Naše oči su osjetljive na određene valne duljine smještenom između 400 i oko 800 nm odgovara vidljivog svjetla. Raspon valnih duljina povezane s tim bojama tvore ono što zovemo vidljivom spektru, ili jednostavno vidljive svjetlosti. Potrebno je da shvatite da se boje proizvodi interakcije vidljive svjetlosti s predmetima koje apsorbiraju neke od valnih duljina, a odražavaju drugima. Dakle, vidimo se "stvari" jer oni odražavaju neke od svjetlosti koja se percipiraju našim očima. Kap krvi vide nas kao crvena jer kad osvijetljen bijelim svjetlom reflektira crveno svjetlo i upija gotovo sve ostale vidljivi spektar. Ako odraz udio svih boja koje čine vidljivom spektru, mi bijeli, u slučaju punog apsorpcije crno. Ćelav orao (Haliaeetus leucocephalus) je porijeklom iz Sjeverne Amerike. Ptica grabljivica obitelji Accipitridae, obično velike, mesojedi, visoka vidna oštrina. Ipak, to je lovio gotovo do izumiranja. Trenutno je zaštićeno i oporavak. Ovaj orao ima smeđu perjem, osim glave koja je obično bijelo. Izvor:. Bald Eagle, na Combe Martin divljih vrsta i Dinosaur Park, smješten u Sjevernoj Devon, England Www.dinosaur-uk Kao što smo rekli, boje su proizvedeni od strane različitih valnih duljina vidljive svjetlosti. No, treba napomenuti da u prirodi postoje brojni valne duljine da naše oči ne shvaćaju, npr.: mikrovalne pećnice, radio valovi, X-zrake, ultraljubičasto zračenje i infracrvene zrake. Štoviše, životinje su dalekovidni valne duljine izvan tog raspona. Orao može vidjeti dio infracrvene i ultraljubičaste zrake pčele nišanom. Zastupljenost elektromagnetskog spektra.
