Reflectivity ranges from 100% to 0%. A surface that seems red, for example, absorbs yellow, green, blue, and violet light while reflecting red light. The least reflecting color is black; it is the color of a surface that absorbs all light. Most things are a mixture of black and other colors. For example, a white tablecloth is mostly black but with some red, yellow, and blue mixed in.
Red is one of the three primary colors used to make any color by mixing them together. It is a type of pigment that can be mixed with other colors to create a range of reds. Even though red is a simple color, there are many ways to describe different shades of it. Dark red is described as maroon, or more specifically, medium-dark maroon. Light red is described as pink, or more specifically, bright pink. Very dark red is described as burgundy, or more specifically, medium-dark burgundy. Very light red is described as orange. Bright red is always scarlet. Each word used to describe red affects how it looks when mixed with other colors. For example, if you mix dark red with white, it will look like maroon. If you mix bright red with white, it will still be red but it will look like fire.
There are two types of red pigment: organic and inorganic.
What is the hue that does not reflect any light? A surface that does not reflect light will seem dull black when contrasted with reflecting material, but will be undetectable when not contrasted. Such a surface is called "black" or "dark". A completely dark environment would have no contrast with its background; thus, it would appear black.
People who work in environments where they are not exposed to sunlight must wear some form of protective clothing to avoid becoming prematurely blind. These workers are called "UV (ultraviolet) light" exposure.
The term "black" applies to many colors, not just black. For example, carbon soot and ink are both examples of non-reflecting materials that take on a black color. However, while black carbon soot looks like true black, ink is more of a gray color. This is because ink contains particles that reflect part of the incident light and therefore give it color.
In conclusion, black is the absence of color. It does not mean dark or without lightness/brightness. Black can be one of many colors - gray, white, black carbon soot, ink, etc.
Our eyes see the wavelength of red reflected from (say) a red shirt made of cotton dyed in red. As a result, this red dye "reflects" red light while "absorbing" everything else. Most colors are absorbed by black, whereas most colors are reflected by white. Black has no color itself; it only absorbs light of all wavelengths.
Black has two important uses in science: as a background against which to view objects (these days this is usually provided by white material), and for absorbing light so that scientists can study what's behind it. Modern black materials include carbon-based substances such as graphite or diamond, but they also include other elements such as sulfur or nitrogen. The color of these materials comes from impurities present in the crystal structure of the solid.
The rainbow is formed when sunlight passes through a cloud layer containing particles with different sizes. Large particles reflect light of all colors except red, which is absorbed due to lack of space within the particle for its spectral lines to form a pattern. Smaller particles allow more red light through, so all parts of the spectrum are visible again after passing through the cloud layer.
Light waves with different frequencies behave differently when passing through a medium such as smoke or air. High-frequency waves pass easily, while low-frequency waves are absorbed.
1 response The only color that is reflected and transmitted is red. All others have been assimilated. Whether it's sunlight, headlights, or streetlights, all objects show up as red against the white background of snow or ice.
2 responses Red is the only color that can be reflected back to its source. All other colors are absorbed by the object they strike. This is why during a sunset or sunrise you see everything in red or orange - because that's all that's left after all the blue-colored light has been absorbed by the clouds or the earth's surface.
3 responses The wavelength of visible red light is about 656 nanometers (nm). It is therefore able to pass through water, glass, and many other materials which cannot pass near-infrared or infrared radiation.
4 responses Red light has a higher frequency than green or blue light; this is why it can penetrate more deeply into opaque objects like trees, walls, and windows. Even though red light is partially absorbed by water, it still reaches the bottom where it is reflected back towards the sky if the water is deep enough.
First, it is not true that an item of a certain hue (e.g., red) absorbs all other colors of light and solely reflects red. In actuality, it absorbs the light of the color complement of the color in which it appears (green light for a red item) and powerfully reflects red. Green items do not reflect green but instead emit it.
However, it is true that most materials have the property of absorbing only specific wavelengths of light. For example, glass filters out blue light and allows red and yellow light to pass through. This property enables us to see what is behind glass windows during daylight hours by preventing these visible wavelengths from reflecting back into our eyes.
The ability of some substances to absorb one type of radiation and transmit another is used in photonics. For example, optical fibers are made from glass and so they will mostly pass light with wavelengths outside the range 0.7-1.4 microns. However, it is possible to add dopants to change this behavior. For example, if you added phosphorus atoms to the core of the fiber then it would also absorb light at shorter wavelengths such as those used for transmitting data signals.
Photons are particles of light. Photons of all frequencies can be absorbed by matter, but only certain frequencies are able to leave the material.
The hue of things The only light reflected from the garment is red light. If only blue light was projected onto a red garment, the shirt would appear black because the blue light would be absorbed and no red light would be reflected. Because white things reflect all colors, they seem white. Therefore, only red light is reflected from the garment.
The only light reflected from the garment is red light.
If you were to hold up a piece of paper under a lamp and shine it with a red light bulb, the paper would look black because red doesn't like to be mixed with other colors and will absorb them. When white paper is exposed to only red light, it looks black because no other color reaches the paper.
This isn't really surprising since we know that red is a color that attracts attention. If something is red, then it's likely to catch someone's eye. That means that if you wear red often, people will expect to see you everywhere red is found!
Here are some other colors that can be seen through a red shirt: black, white, gray, blue, pink, and orange. If you were to walk around with a red shirt on all day long, you would be surprised at how many different colors you would see!
Red has such a strong effect on other colors that if you put red in a painting or drawing, other colors will look brighter. This is called "adding contrast". If there is already much light in your painting, objects will seem dark compared to their surroundings.
