i have a question about colours white and black?

Question

why does the color white more likely to reflect light and heat, and why does the color black more likely to absorb heat?

Answer 1

love and hate

Answer 2

Your question is, “why does the color white more likely to reflect light and heat, and why does the color black more likely to absorb heat?”

Consider a red coloured object. Place it in a dark room and see the color. Since there is no light in the room, you cannot see the object if the room were perfectly dark.
Thus it is evident that only when light falls on an object we can speak of its color.
The color of an object is sensed as red, blue, green etc, only by the light that is coming from the object.
If an objects sends back all the lights (or all the colors) the objects looks white.
If an object sends back no light or all colors, the object looks black.
Now read your question again and find the flaw in your question.

Answer 3

White surfaces look white beause they reflect light. Black surface looks black because it absorbs light. If it did not absorb light, it wouldn't be black.

Totally white and totally black surfaces don't exist.

Heat is also electromagnetic radiation like visible light. So, the behavior of surfaces is similar to both heat and light. However, other electromagnetic radiation like x-rays may not be reflected or absorbed. Thus reflection and absorption are dependent on the wavelength of the radiation.

Answer 4

let me first tell you that black is NOT the combination of all colours and white IS.

because white is the combination of all the wavelengths of light, so what one colour tries to absorb, the other colours reflect off. so all the colours combined reflect of the most amount of light. and the same goes for heat.

...and for black, black is the colour when there is no other colour present, so it absorbs the most amount of stuff since there are no colours present to reflect anything.

Answer 5

There is no such thing as colour really, but in the context of your question, " white" is white because it repels all the photons at all frequencies of light, hence you see the whole spectrum reflected back to you, which results in the "white" colour.

Black does not reflect them. It eats the photons and get heated up.

Take a look at the spectrum of light in the light of energy levels. You will be able to see much better.

Answer 6

Something that no one has mentioned is white is more likely to reflect infrared, and black is more likely to absorb it. This is where most of the heat comes from.

Answer 7

a wall appears white if it scatters all colours in the white light which falls on it
A wall appears black, if it absorbs all colors of white light which falls on it.

Answer 8

because black absorbs all color pigments while white is the product of having to reflect all color pigments...



so white= no color pigments

balck=all color pigments

Answer 9

White is the absence of color and Black is all colors combined.

let me ask you this...what is light?
