Opaque concepts and related words
Definition of opacityA material with opacity when not it lets light in appreciable proportion. It is an optical property of matter, which has different grades and properties. He is said, however, that a material is translucent when it passes the light, but so that shapes are made unrecognizable, and which is transparent when the light passes easily.
That a material is opaque when it blocks the passage of visible light generally, said. For technical applications, discusses the transparency or opacity to infrared radiation, ultraviolet light, x-rays, gamma rays and in each one of them is characterized its opacity function.
Opacity function usually envelops both the frequency of light that interacts with the object as the object's temperature, is important to emphasize that there are different functions of opacity for different objects for different physical conditions. Mathematically the opacity feature is represented with, each function implicitly carries with it the physical mechanism that you want to study.
According to quantum mechanics, a material will be opaque at certain wavelength where there are some difference of energy that corresponds to that length of wave in its scheme of energy levels. Thus, metals are opaque (and reflect light) because their energy bands are so wide that any color of the visible spectrum can be absorbed and re-emitted.
Concept of opaqueFrom the latin opācus, opaque is something dark or gloomy. The term can be used in a physical sense (as a reference to that which impedes the passage of light) or symbolic (linked to sadness or melancholy).
For example: "this opaque stone is used to create elegant jewelry", "I prefer opaque dresses before too colorful garments", "the accident did that last year was opaque to me".
The quality of opaque is called opacity. It says that a material is opaque when not allowing light to pass in a proportion that can be appreciated. It is possible, therefore, to refer to various degrees of opacity. Some terms contrary to opaque are translucent, diaphanous and transparent, which represent the total step or in great part of the light.
The opaque involves a blockage of the passage of visible light. It could be said that the brick is an opaque material: If rises a wall of bricks in a place where the Sun's rays are reflected, such luminosity will not pass through the wall. Instead, a wall of glass Yes allows the passage of light, since the Crystal is a translucent material.
The idea of opaque can also apply to a Government or an organization according to how they manage the information. It will be a Government is opaque if it does not properly communicate the fate of public funds; that is, if the population does not have access to information to account for the use of those funds.
Something opaque, finally, can be something boring or devoid of creativity: "In a dull match, the selected tied scoreless before Costa Rica", "the truth is that I bored much: seemed like an opaque film, dull".
Meaning of opaqueThe opaque word use it very frequently in our language and the colloquial language when we want to indicate that something or someone has no brightness or turns out to be quite mediocre and absent from talent, respectively. Tom Cruise performance in his last film was really dull, I was surprised. Sideboard is opaque, you must wipe wax with a cloth and will lift the natural luster of the wood.
Another job that presents this word at the behest of ordinary language is to indicate when something is boring or does not have enough creativity. The new Harry Potter book was opaque to me.
And on the other hand, we also use the word opaque when it is noted that through such or which body does not pass light, for example, iron is an opaque material, since if you have against the light of the Sun, the same clog it, it will not pass.
Noteworthy is that the quality of opaque is called opacity, by case, when an object or material do not allow the light to pass through them they shall be determined by the aforementioned quality, or block the passage of light completely. Opacity is a typical optical property that has the matter and that can also occur in different levels, or in greater or lesser degree of opacity.
Meanwhile, the antagonistic concept of opaque is the transparent, that he proposed just the opposite, something that is translucent and that then allows to see objects through the abundantly clear; and also usually those people who happen to be easy to decode and predict described as transparent.
A separate paragraph deserves the symbolic use normally attributed to this concept, or that by its reference used to express emotions such as sadness and lamelancolia.
