The reason white light is separated into colors is because light of different colors have slightly different indices of refraction. Thus, for example, red light might be bent a little bit more than blue light.
Refraction can separate white light into the spectrum of visible light from red to violet.

White light is made up of different colors. When white light enters water (like moisture in the air) it is bent (refracted). However the different colors are bent (refracted) by different amounts. So this different amount of bending has the effect of separating the white light into its colors and we see this as a rainbow.lalalalalalalalalalalalalalalalalalalawwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
White absorbs the least light. The "pigment" that causes the color white does not absorb any other colors, so all the colors are reflected back to you as "everything", or white. Think of white light. There are many colors hidden in white light, and by the process of refraction, white light can be separated and a rainbow of colors revealed. Black, on the other hand, is a pigment that absorbs all colors of light. Since no color is present, what you see is essentially a reflection of "nothing".

I think it would hardly make a difference. Please notice that the reason the rainbow is colored in the first place is not related to the color of the water, but to refraction. White light is a mix of colors; the refraction in a water drop separate those.
White light is a mixture of all the colors of the rainbow. When white light passes through raindrops refraction occurs; it changes direction - we see colors because the amount of refraction depends on the frequency (ie the color) of the light passing through the water - this process is called dispersion.
light is white. if you mix the colors of the rainbow you get white. A prism separates the colors, showing a rainbow.
Yes, although the separate colors are perceived to your eye as white. If you have a prism you can separate white light into the continuous color spectrum. This effect is also achieved in rainbows.
White light is split into the color spectrum of a rainbow by a process of refraction, reflection, and again refraction within a water droplet. Technically, the refractive index of whatever surface the white light hits determines how the light is split, and thus the size of the rainbow and the number of colors visible.
Reflection: light bounces off of a surface, like a mirror.Refraction: light goes through a substance and bends. For example, white light through a prism comes out in a rainbow because the light is refracted or bent and each color has a different index of refraction.

Yes. The reason this works is because the index of refraction varies depending on the frequency (or wavelength) of the light.
No, but it can be formed by refraction.
"White" is not a single wavelength of light. It is at least three wavelengths of light to which our eyes are attuned. Matter treats each wavelength differently, so it is possible / likely that a given transparent material will separate the individual colors differently with refraction.
