What is the first color of light that you can see when a piece of metal is heated?
The first color will be red - generally a strong red, becoming more orange as the metal gets hotter.
Does light carry heat?
Yes it could. Haven't you ever noticed that when you keep your lamp on for a long time and you touch it, it is very hot. This is because inside the bulb there is a metal called tungsten (I am not sure if this is the correct spelling). When you heat up that metal to a certain point it starts glowing. Therefore light doesn't exactly produce heat but light produces heat depending on situation. that's it
How the light energy from the stove transformed into heat energy?
light energy is transfromed into heat becaues light is hot For visible light to transfer enough energy to heat some object, you must be talking about laser light. Infra red waves transfer heat because the bodies cells respond to this, infra red is not visible light but has slightly longer wavelengths (lower frequency)
How does white paper reflects heat?
We see color based on the way objects reflect light. Different wavelengths of light are different colors, and the light that an object reflects is what we see. For example, a red ball reflects red light, and so we see the ball as red. Any light that the object doesn't reflect is absorbed, so the red ball would absorb all the light that isn't red. This light then turns into heat. In science, white is the absence of light, and so white objects reflect all light. This means that the object isn't absorbing any light, and so the object isn't absorbing any heat.
Why is red always at the top of a rainbow?
It is the first color in the visible light sprectum. its really close to non-visible light called infrared light (heat). That's why things that are really hot are usually red. It's true that we could look at things the other way around and consider red to be the LAST color (with violet being the first), but going red-to-violet means the lower energy (and lower frequency) wavelengths come first.

What part of light is heat?
Infra red part of light is responsible for heat.
Why do brake pads in a racing car glow red hot?
It is because of friction heating them up and the heat makes it light up so you see it red. It is the same in big car factories they heat up the metal red hot so it is easier to mold.
How to Take spring out of metal?
This depends on the metal, but for most metals, the answer is : heat the metal to red heat, then cool it slowly. This is called annealing. copper is one of the exceptions. To anneal it, get it red-hot then dunk it in cold water.
How do you heat treat or harden a metal chisel?
Heat the metal red hot. To harden the metal, cool it quickly by dunking it into cold water. To get a soft metal, let it cool slowly.

Does toaster have metal?
Toasters are made of metal to withstand the heat from the red hot elements that toast the bread.

What is light produced by heating a piece of metal until it glows?
If you heat a metal it will begin to glow faintly red at around 500ºC, or about 950ºF. If you continue to heat it, by 800ºC (about 1450ºF) the glow will a dull cherry red and at about 1100ºC (about 2000ºF) the colour will be a lemon or light yellow colour. Finally, at temperatures above about 1300ºC (about 2400ºF) the glow appears white, and very bright. Precautions must be taken, as looking directly at an object at this temperature can damage your vision.
Why does light attract heat?
It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. Light = Energy = Heat = Can make light?
Why will the leaves of a red rose be warmed more than the petals when illuminated with red light?
The reason the rose is red is because it reflects red light. So if shining a red light on a red rose, most of the light will be reflected by the rose, but absorbed by the leaves. Absorbing light warms an item.
