It is commonly known that in pictures/videos light coming from the sun can be greenish or blue... sometimes different shades of blue also brownish.

Part of the light is turning back from the surface and part of it continuing into the water.

Our eyes see different wave lenght of light in different colours so the wave lenght of sun light entering into water have to vary in "different waters".

But what actually is the reason for different wave lenght...
- contet of salt
- organic material in water
- unpurities
- some other components in water
- particles
- something else

Do you know something about it?
