Day Time - Night Time Lighting

In all fairness the quote was from an article JB found.

PBQ, your doppler argument made sense but didn't seem to jive with reality. We eventually got to the bottom of it. RTR did seem a little terse, but its a forum, it happens when people type. Let it go…

And not that this really needs to keep going on until dawn (moonlight should be shutting off any minute now), but water isn't blue, its perfectly clear. The blue is just behavior of light in a medium, not a characteristic of the medium.

Have a good night all ;)

EDIT: 3 pages on this, good grief :rolleyes:

I'll not go into details to save people from death via boredom, but I and my chemistry books respectfully disagree with you as to the "perfect clarity" of pure water.

Who'd a-thunk this would've been such a lively discussion....:D
 
Where is the blue? I just don't see it. The light is blue, the water isn't. Not in the same way as an apple is red, for instance. I fear we are edging into semantics at this point… and to no good purpose.
