Water - say it is colorless. Then why are we so attracted by perfect turquoise waters off the Maldives and repels sullen grayness water during a storm?
What water discoloration? This question is asked not only children but also adults, and the answer - the water has no color. It is transparent and clear. But is it the right answer?
Check out this cute glass of water. Except for fish, water is colorless, right? No not like this. Water has a color, just the human eye is not given to catch it.
In order to see the real color of the water, we have to look at the big reservoir.
This can be done in a scientific way, but the human eye can see the rainbow color of the water under the right conditions.
You've already guessed what kind of color? Yes, it is blue, pale blue, or turquoise. Now, think about why you came to mind this color? Because it reflects the sky on the surface of a large body of water such as the sea?
But when the day is overcast, why the color remains the same or even more crowded?
It is true that the reflection of light affects the color of the water, but only when its surface is practically immobile. This photo was taken in Los Cabos, Mexico, and it shows the calm and serene sea - the blue. Red - a reflection, not the color of water.
The brightness of the color depends on the angle at which we look at the water, which in scientific language is called setting angle. In simple terms, it depends on how many degrees you are distant from the water. The higher the angle, the blue water due to reflection. And all because the reflectivity of the water is higher in direct relation to the angle of installation. Water can be a reflective quickly under these conditions.
Of course, that is in the water, it plays a big role in its color. These salt lakes of the United States is full of algae. Pink algae. No, it is not true that the water level is so low pH value, that when the flamingos tried to land there, then simply vanished. In the "blame" a large number of micro-algae Dunaliella salina.
Typically, algae associated with the color green, and it is, of course, changes the color of the water. But it can be done and a person. Chicago residents often change the color of the water in its river green on St. Patrick's Day.
The greatness of the deep blue sea in Montserrat. Most of the color comes from the depth of the water, and does not reflect on its sun's surface. White sun's rays contain all the colors in the spectrum. Water absorbs these colors, but some of them it absorbs better than others. But this requires a "company". In other words, take a cup of sea water, and it will seem transparent, but it is necessary to pour it back into the sea, and she will join the endless molecules of H2O, becoming blue.
The sea water can also absorb infrared light, but because the sea is not red. But the water is not very good at absorbing blue color, so the color is transmitted through the water. Since it is not absorbed, we believe the water is blue.
Yes, this principle also applies to the sky and the blue.
Ferries off the coast of the Maldives in the sea, among its many colors. If you've ever been in the pool with whitewashed sides and bottom, you have noticed that the water seems to turquoise. Even if there is no light that can be reflected.
So the whole thing in the outside world - the best color of the water can be seen from above. And this beautiful picture well illustrates this.
In terms of the visible spectrum, red and blue - complementary colors. So we see a blue color when looking at how color passes through the water at a depth. The lower we go down, the more saturated the color blue.
When divers use flashlights, there are "real" color, but the rest of the distance appears blue, even if in fact it is not.
This color can be seen in deep snow or ice. In the same way, it is possible to contemplate a frozen waterfall - almost blue-green hue.
The visible color contact can also lead that is in the water. Sometimes, in thought looking out to sea, you can see that in different parts of it in different colors. This magnificent snapshot of the Maldives shows the sea raznotsvete. It can be caused by the presence of clouds and their shadows, but often is not the case (especially in clear days). It comes from the fact that is in the sea, rather than over it.
The image of Liguria in Italy perfectly demonstrates the different shades of the sea.
Typically, oceans and lakes contain a plurality of particles in the water. This combination of dirt and dead plants and animals. Living organisms, also because of its size, can change the way we perceive the color of the water. When water can not absorb a lot of blue, it affects these elements in the water, and the blue light is reflected back to the top. Tropical waters and, for example, waters of the Atlantic Ocean are different from each other, because in the tropics color comes from the absorption of red, leaving us only see blue.
In this amazing wave you can see all the colors of the water off the coast of Guadeloupe. The water in the Atlantic Ocean, on the contrary, has a blue hue, caused by the suspension of the myriad of plants, animals, and partial dirt.
Why are some bodies of water is not blue? Some black or gray or brown. Again, it depends on the fact that water is absorbed. The turbidity of the dirty water can be explained by scientific methods. Dirt affects more red in color than blue, so that when water is present in the dirt, it becomes brown.
The lake is full of peat will look black, as the peat absorbs vertically all the light that falls on it. On a cloudy day, the sea seems gray and, yes, it kind of depends on the sky. This is also because the clouds filtered the red light from the sun before it reaches the water.
We see the water in different statuses. It may be colored particles, the presence of bacteria or reflection of the world on the water surface. Ice and snow may provide a deep rich blue color, such as Multnomah Falls in Oregon. Water itself is blue, which appeared as a result of its molecular structure and behavior.
There is clearly visible blue color, when a pair of climbers conquer the mountain in Banff National Park in Canada.
Of course, the water in Banff National Park, known for its turquoise color. All thanks to the particles of rocks in the melting glaciers. Moraine Lake is known for its incredible blue, from which almost reduces eye.
If you want to look at the natural color of the water, it can be done at virtually no cost. Take a long tube of pure water. So that the water does not leak when you look at it, then close each hole glass.
If you look down through the first "window" on a piece of paper, illuminated by sunlight, you will see the pale blue waters of shade.
