A substance that appears black (in a lighted room) is absorbing all of the visible light that hits it, leaving no visible light to reflect off of it to your eye. So it's absorbing visible light of all wavelengths. (You still don't know what's happening to the infra-red or ultraviolet hitting it. For that, you need to use different detectors.)

What must happen to all wavelengths of light for a substance to turn black?

All wavelengths of light must be absorbed by the substance for it to appear black. When no light is reflected or transmitted, the substance appears black because no color is perceived by the human eye.

What color are objects that absorb all colors that reflects little light?

Black objects absorb all or most of the visible wavelengths of light, whereas white objects reflect all wavelengths. When all visible wavelengths (violet to red) enter the eye in equal proportions, the color is perceived as white. When no wavelengths reach the eye, the color is perceived as black. Every other color is a mixture of this continuum of wavelengths.


How is color reflected?

Color is reflected when light strikes an object and some wavelengths are absorbed while others are reflected. The reflected wavelengths determine the color that our eyes perceive. Objects appear white when all wavelengths are reflected, and black when all wavelengths are absorbed.


Why are the clouds black?

Clouds appear black when they are thick and dense, blocking out sunlight and making them appear dark. This can happen when there is a lot of moisture in the air, causing the clouds to absorb more light and appear black.

For a substance to appear black what must happen?

i think that it must reflect red light waves.


What color is a substance?

The color of a substance depends on how it interacts with light. Substances can appear different colors based on the specific wavelengths of light they absorb and reflect. For example, a substance that absorbs all wavelengths of light appears black, while a substance that reflects all wavelengths appears white.

Why sunlight turn black colour into white?

Sunlight cannot turn black into white. However, a black surface may appear white in bright sunlight due to reflection of all the wavelengths of light from a shiny surface. The color black is actually the result of the absence of reflection of any wavelengths of light while the color white is the result of reflection of all the wavelengths of light.

Does black paper absorb wave lengths of light?

No black paper is not translucent ts opaque


What colour would the grass appear under orange lights and why?

The grass would appear black under orange lights because green objects appear black under light that does not include green wavelengths. Orange lights contain little to no green light, causing green objects like grass to absorb most of the light and appear as black.


Why does the black colour has more power to absorb the wavelength of heat?

Substances are black because of the fact that they absorb various wavelengths (frequencies) of visible light, rather than reflecting it back. If a substance reflects back (rather than absorbing) all of the wavelengths of visible light, then it appears white. Since a black substance absorbs energy rather then reflecting it, that energy goes into the molecules of the substance, themselves, which gives them energy...in the form of heat. Whereas, if it were to reflect it back, that energy would be re-emitted, and would not increase the temperature of the substance.


Why black body absorbs heat?

Objects appear white when they reflect all wavelengths of visible light. Reflection of various wavelengths of light means that they are scattering the light back into the space surrounding the object, rather than absorbing that energy.Objects appear black when they absorb all wavelengths of visible light, thus absorbing that energy (some of which is converted to heat).
