Because the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up. Violet travels the slowest so it is on the bottom (least bent) and red travels the fastest so is on the top (most bent).
If you mean light, then all colours are the same velocity, but different frequencies and wavelengths.
Red. Policemen will pull over red cars at a far greater rate than others. So maybe they at least look faster, or the color red makes them angry like bulls. Torro!
violet (blue)
I could say that shorter wavelengths move faster, but that would be wrong.
The truth is that all wavelengths/colors travel at the same speed.
All colors of light have the same speed in air, but its
speed in air is not the maximum speed of any color.
Air is colorless.
black because black heats the fastest
Yes black ink radiates more heat than white paper. This is because more heat is absorbed by black ink more than white paper and it is required to radiates more heat due to its heat capacity
Water absorbs and radiates heat better than soil does.
the sun has many radiates. that's cool. :)
The earth re-radiates energy when it can. The earth absorbs solar energy, but constantly radiates heat back out into space. When the earth rotates, the "non-sun" side is facing the cold of open space, and the surface of the earth radiates a whole bunch of heat out into the darkness of space. That's why it usually gets cold at night - all that energy is leaving.
Most car radiators are black as black radiates heat more efficiently than any other color.
It's one of the colour. Black colour absorb all colour. A perfect black body radiates heat.
Within the lifetime of a star, its colour, its size, and the amount of heat it radiates will all change.
red because it's the colour of fire
All of them.
By Fusion.
It conducts or radiates
Why not? Blue is good colour. :) It radiates determination!
Clouds don't really heat the Earth. Some clouds keep the Earth from losing heat. Heat is moved in different ways. One way is radiation. The Sun warms the Earth with radiated heat. But, the Earth also radiates heat. Clouds absorb some of the heat the Earth radiates and radiate it back to the Earth. If there are no clouds present all of the heat the Earth radiates go out into space and is lost.
because it radiates heat
yes
Dull Black Surfaces
because it radiates heat.
