colourless object?

Question

red object appears red due to the absorption of wavelength of the red colour.
How about the colourless object???
What is the range of the wavelength the colourless object absorb??
thx

Answer 1

say glass i think it just passes through and no absortion occurs

Answer 2

Actually red objects absorb every color but red, and reflect red back at you.

Colorless objects don't reflect visible light coming at it from most angles, but allow it to pass through. The reason you can tell they are there at all is that the light bends as it passes through, thus making things behind them look weirded. Black objects absorb all light, and white object reflect it all.

SOme transparent objects may reflect colors in the non-visible spectrum. That's how you make UV protective eyewear. Most absorb infra-red, and some amount of the visible spectrum moving through, which is why a glass will get warm.

Answer 3

Your initial logic contains a flaw. A red object appears red because its surface _reflects_ red, and absorbs all other colors. White reflects all, black absorbs all.

The colorless object? There is none. If you can see the object at all, it reflects something. Even air contains the propensity for color, and reflects some (consider the slight blueness of distant mountains).

If you're talking about something like a glass marble, it reflects little and refracts most color.

Answer 4

Colorless objects do not scatter the transmitted light. If objects scatter all the light, they would appear white. If objects absorbed all the light, they would appear black.
Our perception of color is based upon the degree of reflected, absorbed or scattered light or some combination of these.
A colorless object is said to be transparent. If it appears a color, it is translucent.

Answer 5

Mike's answer is correct. The "cones" in your eyes see colors. They require a lot more light to function than "rods" do. Rods are your night vision (and animals' as well). Rods are not sensitive to colors, though, so that's why everything is in black and white - because the part of your eye that sees color isn't getting enough light to work properly. The moon reflects pretty much the same wavelengths (colors) of light that the sun puts out. It is grey, which means that it reflects all colors, but absorbs some of the intensity. It seems brighter under a full moon than it really is because your eyes adjust to the low light conditions to let in lots more light than they do in the day time, but it is very much darker at night, even under a full moon.

Answer 6

red object reflects red light. not absorb it. by colorless i'll asume that you mean clear, clear doesn't reflect or absorb any of the light, it passes through.

Answer 7

i think all of the colors mixed together makes white... or all of the colors mixed together make black.... not sure. but on a clear object... i think that the wavelenghts go right through it...?

Answer 8

it reflects all the light come to it
