Black or dark colored materials and objects radiate (give off) and absorb heat the fastest. The reason for this is that lighter colors reflect more light. Instead of thinking of dark colors as absorbers of heat, darker colors are actually better absorbers of light.
Violet light has the shortest wavelength, and so it has the highest level of energy of visible light.
When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
Based on the recorded temperatures, the clear water absorbed the least amount of heat from the sunlight, while the blue water absorbed the most heat. The specific order from least to greatest amount of heat absorption is: clear, orange, yellow, red, green, purple, and blue.
Violet has highest energy.
Your brain interprets the various energies of visible light as different colors, ranging from red to violet. Red has the lowest energy and violet the highest.
If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.
Which color absorbs less amount of energy? The specific order from least to greatest amount of heat absorption is: clear, orange, yellow, red, green, purple, and blue.
Light colored clothing reflects most of the visible wavelengths which, in turn, absorbs less heat. On the contrary, darker or black clothing absorbs more wavelengths, absorbing more heat, hence making the clothing warmer to wear.
Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
Energizing colors
Strong, bright colors and neon colors can have a powerful effect on emotions. Colors like bright red, bright yellow and neon green can feel energizing and make you feel more alert, but can also be irritating on the eyes.
Lighter Colors Equal Lower Costs
For the exterior walls of the house, colors that support improved energy efficiency include white, beige, light gray and the lighter variety of other neutral colors. These colors reflect radiant solar heat rather than absorbing and retaining it.
Dark or bright colors
Darker colors absorb more UV than lighter colors like whites and pastels. This means the UV rays are less likely to reach your skin. But bright colors such as red can also absorb UV rays. The more vivid the color, the greater the protection—a bright yellow shirt is more protective than a pale one.
So what about gray? That depends on how light or dark, dull or bright of a gray you select for your home's exterior. Lighter, brighter grays will reflect more light and heat than a darker, duller gray, meaning gray is a viable option for either impact on the interior temperature.
1. Wear White. A white object is white because it reflects white light, and white light is a combination of all the visible colors. This means that a white shirt (or pants) will reflect most of the light and not get hot.
Black objects absorb all colours so no light is reflected. Rights: University of Waikato.
Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
Sorbothane® has been recognized as the highest performance, energy-absorbing material since 1982 and is recognized as the industry standard. Consider Sorbothane's unique properties: A high tan delta value or damping coefficient.
White is a bad absorber of light because it reflects all colors, not taking in any light energy. It only reflects the color waves, meaning that it's not absorbing much heat, and therefore that makes it the coolest color.
White, silver, and other light colors are coolest, reflecting about 60 percent of sunlight but there are dark "cool" colors that can also stay cooler than traditional dark colors.
Dark or bright colors, including red, black and navy blue, absorb more UV rays than lighter colors like whites and pastels. For example, an everyday white cotton T-shirt has a UPF of only about 5. As a rule of thumb, the more intense the hue, the better protection the clothing will provide.
Detailed Solution
The correct answer is Green.
Each light frequency (that is, each colour) carries a particular energy, and if that energy is precisely the right amount to knock an electron from one state to another within a molecule, that frequency will be absorbed.
Violet light has the highest energy, frequency and vibration and the shortest wavelength of visible light. Beyond the visible spectrum, ultra-violet is even shorter wave and higher frequency and energy, in fact its energy is so high it can burn our skin very quickly and kill bacteria.
