Question

How does fire emit light (the sun, a candle, a fire, etc.)?

In: Physics

Answer 1

Everything emits light. The light is different colors depending on its temperature.

If something is ~~too hot or~~ too cold, then the color of light it emits is not a color our eyes can see. But if it is just hot enough, the light it emits is a color we can see.
