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.)

If light of all visible wavelengths is combined the results appear to be what color?
If the lights from all visible wavelengths are combined, they appear to be a white color.
How can you have different types of light?
Different wavelengths of light (photons) appear of different colour to our eyes.

must be reflected
For a substance to appear black what must happen?
i think that it must reflect red light waves.
If light of all visible wavelengths is combined the results appear to be what color?
If the lights from all visible wavelengths are combined, they appear to be a white color.

Different wavelengths of light (photons) appear of different colour to our eyes.
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.
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.
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).
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.
What must happen to all wave lengths of light for a substance to appear white?
The colours we see in an object are only the colours that are reflected. Inferentially, the other colours are absorbed. The grass is green (when illuminated by a white light source) because the redder end of the spectrum is absorbed and used by the plant to do its stuff - photosynthesis and so on. A white card appears white because all the light wavelengths [to which we can respond] are reflected. That card may absorb some of the white light, but not at wavelengths to which we respond.
