1 milliwatt of light carries 1 milliwatt of power, and delivers 0.001 joule

of energy per second to anything that completely absorbs it. The source

of the light doesn't matter.

What is hotter black or white?

Black surfaces absorb more heat and light than white surfaces, which reflect most of the light that hits them. Therefore, in terms of temperature when exposed to sunlight, black is generally hotter than white. However, the perceived temperature can also depend on other factors such as the material and environment.

Yes it does. Black absorbs the most light. That is why in a car, for example, black seats are hotter than white or tan. Also the material matters as well. Rougher surfaces absorb more heat than smoother surfaces. That is also why leather seats absorb more light, or heat, and feel hotter than other material seats.


Is white hot hotter than red hot?

Yes. Red comes from the lowest energy range of and blue from the highest. LMAO So when an object gets hot enough to glow it produces red light first. As the object gets hotter it begins to emit yellow, green, then blue light. But it doesn't stop producing the red light either. So when the object is very hot it is producing red, yellow, green, and blue light. Since white light is all the colors combined, the object looks white.
