The Question Box

Prove it and I will admit to it.
But what I said is something someone told me a very very long time ago.

It's the angles of the light. When refracted, white sunlight turns into separate colors (say, from a prism, or a drop of water.)

Red light ALWAYS goes "up", Blue goes "downward" from the source.

PHP Code:



NOON:  


          (SUN)

         (WATER)

red 
     green 
           blue
             |
             v

          EARTH 


PHP Code:



SUNSET:  


         

                     

EARTH    <-     red 
                   green             (WATER)      (SUN)
                          blue 


Is that also what causes green flash?

Right! You'll rarely get the right amount of moisture, and the angle is VERY difficult to get, but that's what happens..

PHP Code:


.....R    Sun
      G    
       B
   /
Earth



............R
Earth  --      G    Sun  (Green Flash!)
                 B



Earth....R 
             G     Sun
               B 


Edit: Darn, tough to fix the right angles.. but I think you can figure this out..

seriously the sky is blue due to reflection form the water but i dun know why the ocean is blue(well thats what i thought i heard from life) and when diving as u go deeper the ocean goes green... not blue but green so i dun understand the light refraction bit u sure blue goesdown?

Water IS blue due to the reflection of the blue sky (not the other way around.)

It goes "down" relative to when the sun is at noon.. it's based on angles (I forget the exact angles, though.) It's actually more a blue with a slight greenish tint to it.

PHP Code:


BLUE-GREEN is much more blue, than green.
RED is refracted at such a high angle, you can't see it.

                   SUN

              WaterVapor   
RED       /        |         |
       GREEN   BLUE-GREEN  BLUE

uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu  (water)
   (still mainly blue, but so much water= more diffraction)


                 (water)           BLUE 
     
                     BLUE-GREEN 
           GREEN

It is REALLY hard to explain this in 2 dimensions, but..

It's called cyan.
I don't get why we lie to our kids in elementery school.
The primary colors of paint are not red, yellow, and blue, they are MAGENTA, YELLOW, and CYAN
They are the oposites of the primaries of light because the pigments absorb the primaries and leave the oposite...
