Water is blue because of selective absorption in the red part of the visible spectrum. The deeper the water the darker it will be. A lake is blue because of how deep it is. A cup of water looks clear but it really is still tinted blue you just can’t tell because it isn’t deep enough. Selective absorption, it only takes certain wave lengths of the red spectrum and the opposite color to red is blue on the visible spectrum. Selective absorption happens because the elections in an atom have a natural frequency and light waves have a natural frequency also they both vibrate. Both of them vibrate together and the electrons absorb the light. And the vibration of that electron and the others turn it into thermal energy.

In this picture the water looks as it is clear but really it’s still blue as I have stated in the paragraph above.  Deeper water means darker color
