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.

Does light refract more when going through a thicker substance?
well three things happen when light strikes an object Refract Reflect absorb
Why do we use infrared light for spectroscopy?
Infared (IR) and the entire spectrum are used to excite molecules and cause them to gived off a signature of various wave lengths of light. Some things show up in the far red (invisible) band. Some show up in the visable and ultraviolet parts of the light spectrum. It depends on the substance or substances as to what light wave lengths you will see. Every substance has a specific signature of colors. We can look at the stars. Prismatically spread the stars light and see what it is made of. The light can be shifted by the speed of the star and weather it comming at us or going away.
What happens when you shine a light through a fog what is this called and why does it happen?
The fog is called a colloidal solution. When light is shined through this colloidal solution, the light scatters in all direction because of the substance contained in this solution type.
A substance that absorbs light?
Pigment :|]
What is a substance that dose not transmit light?
An opaque object does not reflect light. Opaque objects absorb light.
For a substance to appear white what must happen to all wavelength of light?
must be reflected
What substance to appear white what must happen to all wavelengths of light?
must be reflected
For a substance to appear black what must happen?
i think that it must reflect red light waves.
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.)

When light given off by a simple burning substance is viewed through a spectroscope it would appear what color?
A spectroscope is a device for producing and recording spectra for examination. When light given off by a simple burning substance is viewed through a spectroscope, a certain color will appear.
What will happen when white light falls into an object?
It will be illuminated. Whatever else may happen depends on the substance the object is made from.
Why do red nucleus appear red?
As with any material or substance, the apparent color is merely the result of light wave frequencies which are reflected by said material or substance.
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.

How can light refract?
Light hits a substance. The substance makes light change speed. Light gets scattered through the substance. Then the light bends.
