Dear rupen

Our atmosphere and all its water molecules act like microprisms, separating the white light (which is the combination of all the known primary colors) into the separate primary colors. The colors except blue continue down to earth; but blue is absorbed and re-scattered in the atmosphere, and that's what makes the sky its color.

there are several theories why coloe of ocean is blue

1.Blue wavelengths are absorbed the least by the deep ocean water and are scattered and reflected back to the observer’s eyes

2 The ocean reflects the blue sky
