The medium through which it passes
Yes, colloids scatter light. Colloids are mechanical mixtures; all mechanical mixtures scatter light. Solutions are the only mixtures that do not scatter light. The scattering of light by mixtures is known as the Tyndall effect, btw.
Air molecules scatter, that is, they scatter sun's light into all directions. This results in different colors of white light to split into all directions, making blue color split the most, leading to the formation of blue color.
not material, but color. the color black absorbs all colors in light and reflects no light to enter your eyes. black is only visible by contrast on other things you can see.
Any small slit will scatter light. Especially blue light.
no
translucent
they are able to scatter light
A prism
its a solution

Each colour of light has a different wave length which are affected differently by refraction so they spread out and 'scatter'.
Cause they do
