Reason Why Sea Has Color

Monday, October 10, 2011

If an object can emit light and objects that emit red light, then the object would look red.
Meanwhile, if an object can not emit light, then the object would appear in color in accordance with the color spectrum of the reflected object.
Meanwhile, the color spectrum that is not reflected will be absorbed by atoms or molecules making up the object.
For example, when illuminated with white light, the leaves will reflect the green color spectrum than the spectrum colors absorb light green leaves look so green.


Then why is an atom or molecule absorbs certain light?
Absorption only occurs if the incident photon energy matches the energy required to move one electron outside the atom or molecule from ground level to excited levels (or from the valence band into the conduction band in solids).
So the absorption spectrum of colors by the constituent atoms or molecules of an object that causes the object reflects a specific color only.
The spectrum of colors that are not absorbed, will be reflected.
And the spectrum of the reflected color is visible to the eye, and make the object to be colored.

Water also Has a Color


Then why is there a clear object alias is colorless like water.
However, it turns out water and other translucent objects actually have color.
Keep in mind that water color is blue, because the water absorbs the sun's light wave (which consists of seven elements of color).
Water molecules are then absorbed the colors and reflects blue color spectrum, and that is visible to our eyes.

But we may not be able to see the blue water was only on the glass of water or a bucket of water alone.
Because the layer of water in the glass does not absorb and reflect enough of the color spectrum that comes to him, so that water can not show the original blue color.
Another case when we look into the swimming pool or even ocean.
The water will reflect the blue color spectrum and absorbs the other colors of the spectrum so that the water appears blue.


With this it is clear why the sea water or water in a swimming pool blue.
However, in addition to the reflected blue water itself, the oceans also contain many other particles.
Starting from the fish, corals, plankton, and so on.
There is also dissolved organic substances in water.
These materials is the one who causes the absorption of sunlight leaving only a dark blue for the ocean.
In addition, the reflection of blue sky in the water also helped to give the role of the blue color of sea water.

Is not a problem when you try really hard but your ambition is not achieved yet. The problem is when in the middle of the road, you despair the opportunity from the Most Benevolent God's gives to achieve your ambition.
