What must happen to all wavelengths of light?
There a couple things that must happen to all wavelengths of light so that a substance can reflect white. The substance needs to be able to reflect each wavelength equally and the wavelengths must hit it at the same time.
What must happen a substance to appear black what must happen to all wavelengths of light?
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.)

must be reflected
For a substance to appear black and what must happen to all wavelengths of light?

Is black as black a colour?
No. It is the absence of all the wavelengths of light (colors).

What happens when a substance absorbs light?
When a substance absorbs light the wavelengths that correspond to that color cannot be seen. Only colors that are reflected are visible.
For a substance to appear black what must happen?
i think that it must reflect red light waves.
Does black paper absorb wave lengths of light?
No black paper is not translucent ts opaque
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 does not white light when falls on objects makes them appear as black or white?
Many objects do appear black or white when light falls on them. If they are black, it means that the object is absorbing all wavelengths of visible light and not reflecting any. If they are white, it means that they are reflecting all wavelengths of visible light and not absorbing any. The color of an object is due to the wavelengths of light that it reflects.
What is the color associated with reflection?
White. Black absorbs all colors of the light spectrum and thats why it feels hot and looks black. White objects reflect all forms of light, therefore they are cooler in sunlight. An objects color is determined by what color of light it reflects. Since white is all the colors combined, if a substance reflects all the colors then it appears white. If another substance absorbs every color except for 1 shade of red, then the substance will appear that exact shade of red that it reflects.
Which term describes substances that absorb some wavelengths of light?
Pigment is a substance that absorbs some wavelengths of lights and reflects other, giving something its color. Chlorophyll is the green substance that absorbs light and provide energy for photosynthesis.
