Yet only 2% of the color observed on the surface of the water is due to celestial reflections!<\/p>\n<p>In fact, the explanation for this phenomenon lies rather in the absorption properties of light by water molecules. Sunlight is composed of several wavelengths that make up the spectrum of visible colors. Longer wavelengths such as red, orange and yellow are absorbed by the water molecules they pass through. Blue is the only one to be reflected and dispersed to our eyes.<\/p>\n<p>However, be careful! Water absorbs weak wavelengths. So you need very large quantities for blue to appear. That's why the water in your glass is transparent to you. In addition, the water must be pure enough, because if it contains too much suspended particles, its color absorption properties will be altered. In the presence of sediments or algae in large quantities, the bodies of water can be green, brown or even sometimes red!<\/p>","appParentPermlink":"pkuxgwkex","appCategory":"Question","appTags":["Question",""],"app":"Musing","appParentAuthor":"sony1992","musingAppId":"aU2p3C3a8N"}" |
