A sheet of red paper will look black when illuminated with what light?
A red sheet of paper will appear black when illuminated with cyan light, which is the complementary color of red. When the paper is exposed to cyan light, it absorbs all the complementary color wavelengths and reflects none, making it appear black.
Why does a white piece of paper appear white in white light red in red light blue in blue light and so on?
White surface reflects all wavelengths of visible light spectrum (ie. white color is a mixture of all the other colors). If the light that falls on the surface has one specific wavelength, only that wavelength occurs in the light reflected.
What color light will make a red sheet of paper look black?
Any light that does not contain the primary color red will make the sheet of paper look black. (for example green, blue, cyan,... but not yellow, violet,...) This is because the surface of the sheet is such that it absorbs all the colors of white light except red which is reflected and which is why it appears red in white light.
Why Black paper absorbs more heat?
Black paper absorbs more heat because it has a darker color, which means it absorbs more light energy. Light energy is converted into heat energy when it is absorbed by an object. The dark color of black paper allows it to absorb more light across different wavelengths, resulting in more heat absorption compared to lighter-colored paper.
What color will paper appear to be under a red light?
Paper will appear to be black under a red light because red light has a long wavelength and is less likely to reflect off the white surface of paper.

What will be the color of a paper containing red pigment when yellow light shine on it?
The paper containing red pigment will appear red when yellow light shines on it. This is because red pigment absorbs most colors of light except red, which it reflects. So, the red pigment on the paper will reflect red light and appear red when illuminated by yellow light.
Why Black paper absorbs more heat?

Why does black paper appear black?
the black colour absorbs all the colour and reflects nothing.this is why it appears black in colour. :) lillyXOXO
What happens if you shine red light on black paper?
If you shine red light on black paper, the black paper will absorb most of the red light and appear dark. The red light that is not absorbed may be reflected or scattered, but it will not significantly change the appearance of the black paper.
Does the color of paper effect the amount of heat it absorbs?
Yes some colors will take the light for itself and some color reflect the light! Black will absurb the most and brown is the least.
What is special about the colour black?
The color black as we know it, is actually the absence of color. When a "black" piece of paper is hit with the entire spectrum of visible light, none of that light is reflected back to your eyes, so the color of that paper appears "black." The other type of color people sometimes use interchangeably (and incorrectly) is projected color, like the colors on your monitor or television. Black in this case is not a true (scientifically) black, since you cannot project "zero colors," which in this case would be black (note that the area between stars is black). Your monitor is projecting a very, very dark shade of gray and your eyes sees it as black. Black is special because it is not a color but the absence of color.
When a light is passed through a yellow translucent paper yellow light comes out And when further it is passed through a different Colored paper what color will the light emerging have?
No light will emerge from the different color paper, since all other colors except yellow have already been removed by the first one. The second one appears black.
Why does white paper glow under a black light?
White paper appears to glow under a black light because the phosphors in the paper fluoresce when exposed to the ultraviolet light emitted by the black light. This causes the paper to emit visible light, creating the glowing effect.
