Water is not really blue

The framework my opponent presented is partially acceptable. We should base our arguments on scientific argument, especially considering the topic at hand. However, plagiarizing is not an acceptable practice on DDO (or anywhere else.) Quoting an article is fine, but take care not to pass off someone else's words as your own. (You did do this when after the quote when you said "In other words..." Please mark off clearly when you are quoting an outside source. As per the opponent's R1 structure, this Round is for presenting arguments and next round is for rebuttals. Therefore, I will not be addressing the opponent's arguments until next round. Water is BlueI will be demonstrating that water is intrinsically blue. In other words, I'll be proving that pure water has the quality of being blue, by the very nature of what water is. This fact is actually referred to in the opponent's first source by the Scientific American. Here it says, "The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue..." Here the article clearly states that water itself absorbs non-blue light more strongly than blue light, thus giving water its blue appearance (in large quantities.)Of course, selective absorption of varying wavelengths of light is exactly what makes something have a color. If you paint a canvas entirely blue, it appears blue because the paint is not absorbing blue light, thus reflecting it. The same goes for water. The Unique Blue of WaterWater is actually very unique in its 'blueness' as it is the only known natural substance whose color is due to changes in vibrational states, rather than interactions with electrons. [1] This is particularly interesting, as it means the color of water is entirely due to the chemical structure of water, rather than the state of the electrons present. (Why water is unique in this way isn't particularly relevant to the debate, but it's interesting enough that it's worth being mentioned.)The Appearance of WaterThe last point that should be made concerns what color water appears to be, versus what color it actually is. Water is fairly translucent, in that one can see through it. This does not preclude the possibility of water having color as many known substances exist which obviously have a color but can also be seen through. (Rose colored glasses are an excellent example.) If you were to fill a glass with water, it would not seem to have a color. This is because water is only very slightly blue. The blueness becomes more obvious when you look at a larger sample of water, such as the ocean or your local aquarium. A similar substance in this tune is glass. While glass also appears clear in small quantities, if you look at a larger sample (like a block of glass) it becomes apparent that glass is actually green (due to iron impurities.) In the case of water, looks really can be deceiving. ConclusionThere really isn't much more to my argument than what's been presented. I used my opponent's evidence and my own to demonstrate that water is intrinsically blue, thus effectively negating the resolution. I look forward to my opponent's rebuttal and I look forward to offering my own. Sources:(1) - http://www.dartmouth.edu...
