__**WHY DOES WATER LOOK BLUE?**__

Answer the question below, append new answers to the top of this page. _ __Response 1:__ The reason that water looks blue is the same reason why the sky looks blue. It looks blue because red, orange, and yellow, which are long wavelength lights, are absorbed more powerfully that the colour blue is. The colour blue has shorter wavelength lights. Wavelength means "the distance over which the wave's shape repeats." When the white light from the sun enters the water, the blue is what gets returned.

__Response #2:__

Have you ever wondered why water appears blue? Well, you don’t have to wonder any more because here is the answer: As the Sun shines high in the sky it is sending beams of light down onto Earth. Although these beams appear to be bright yellow these beams actually consist of many colored wavelengths. These coloured wavelengths are represented as ROY G BIV, B meaning blue. As the Sun shines on Earth these wavelengths are scattered across our planet. When these wavelengths penetrate water all colors are absorbed, but the blue wavelength is very weak when it comes to absorption. As colors such as red, which is absorbed strongly enter the water, blue is left behind causing the water to appear this color. If you find this to be difficult to understand, think of it this way. The sky is blue because blue wavelengths are scattered at a much higher rate throughout our Earths surface. This is almost the opposite when thinking of why water is blue? Water is not able to absorb a lot of the blue wavelengths leaving the water to appear blue because all other colors are absorbed strongly.
