If water is transparent why does it have a shadow?

Question

I mean for example when you turn on the tap, it has a shadow on the sink bowl.

Answer 1

Water is made out of small transculent molecules (H20) but when they all act together in a body, as water does, and as with anything else, a shadow is created.

Answer 2

Water is transparent to a certain amount, like glass. They always absorb a little bit of light. Transparency also changes with the incident angle! Another effect is that you have also reflectivity of "transparent" materials, which also changes with the incident angle!

Answer 3

It does so because it does not pass light at the same efficiency as does the air, therefore it refracts it. Any change in light travel via refraction is detectable to our eye for the most part.

Answer 4

thogh water is transparent it is made of hydrogen and oxygen and when they get together i thnk they can reflect light as well as as let them go through too a the same time.

Answer 5

Water has the chemical formula H2O meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. It can be described ionically as HOH, with a hydrogen ion (H+) that is bonded to a hydroxide ion (OH-). It is in dynamic equilibrium between the liquid and vapor states at standard temperature and pressure. Water alone is a colorless, tasteless, and odorless liquid, but upon standing it takes on the traces of carbon dioxide in the air and trends toward a sour solution of carbonic acid that is unpleasant-tasting and more inhospitable to life.

Water is often referred to in the sciences as the universal solvent and the only pure substance found naturally in all three states of matter; however, "found" should not mean that water is the only such natural substance that can be in three states at regular Earthly conditions, as its two elements are much more abundant than those of at least ten other molecules that share water's range but that are often found dissolved in water or shale. Examples are acetic acid, formic acid, hydrazine, dioxane, and benzene.



Color:
Water strongly absorbs infrared radiation. As infrared radiation is next to red-colored light on the EM spectrum, a small amount of visible red light is absorbed as well. This results in pure water appearing slightly blue, when seen in mass quantities such as a lake or ocean. The blue color can easily be seen as one sees the blue color of the sea or a clear lake under an overcast sky, which means that it is not a reflection of the sky. In practice, the color of water can vary strongly, depending on impurities. Limestone turns bodies of water turquoise, while iron compounds turn it red/brown and copper compounds create an intense blue. Algae commonly colors water green.



Surface tension:
Water has a high surface tension caused by the strong cohesion between water molecules. This can be seen when small quantities of water are put onto a nonsoluble surface such as polythene: the water stays together as drops. On extremely clean glass the water may form a thin film because the molecular forces between glass and water molecules (adhesive forces) are stronger than the cohesive forces.

In biological cells and organelles, water is in contact with membrane and protein surfaces that are hydrophilic; that is, surfaces that have a strong attraction to water. Irving Langmuir observed a strong repulsive force between hydrophilic surfaces. To dehydrate hydrophilic surfaces—to remove the strongly held layers of water of hydration—requires doing substantial work against these forces, called hydration forces. These forces are very large, but decrease rapidly over a nanometer or less. Their importance in biology has been extensively studied by V. Adrian Parsegian of the NIH.[2] They are particularly important when cells are dehydrated by exposure to dry atmospheres or to extracellular freezing.



thts why its transparent.

Answer 6

nice question.........!!!
it's the same as if we hold a transparent paper in front of a window for example..if has a shadow.....
I know I didn't answer but the only thing in my mind now:
it's made of mulecules...they must have shadow!!!!
..... ....................................................................................................

Answer 7

because water refracts light
