The answer has a lot to do with why you call it "red paper". Could that be because
the paper absorbs light of any other color, and reflects the red light toward your eyes ?
the part the red light touches will turn red...like if u get a red laser pointer and point it at a white paper.
You get magenta.
The red paper absorbs all of the other colors in the spectrum and reflects red so that is the color it appears to be.
because the light goes throught it and you see the light on the paper i think...
red

red
The paper appears black. -- The paper is called "green" because it absorbs any light that isn't green, and reflects only green light to the observer. -- The filter is called "red" because it absorbs any light that isn't red, and transmits only red light through to the other side. -- There's no red light shining from the paper into the filter, so there's no light leaving the filter. The paper appears black.
Nothing - red litmus paper indicates the presence of bases.
Red litmus paper is used for alkaline solutions.
the light becomes red :-P
any light that's not red or white
The surface will look Red, because white reflects all colours and absorb none. If you hit a red light on, say, green then that would look black because green will absorb all the red but if it was a green light then it would look green. Every colour, except white, absorbs colours except itselves.
Nothing particularly happens.
