    Infrared
In summary, the conversation discusses the possibility of using a material to make a heat source undetectable by infrared. The participants also consider the heat level and thickness of the material, and note that any material that shields infrared will also trap heat. Additionally, the conversation mentions using this material to cover lamps in a room to make the heat undetectable by infrared.

Is there a material that can effectively make a strong heat source undetectable by infrared, by covering it (the heat source)? A random question, I know - just curious.

How hot are we talking about? How thick can the material be?
 
  • #3
Any heat insulating material of sufficient R value will.

It should be noted that any material that shields the infrared appearence of the heat source would also trap the heat. Something to bear in mind if the purpose of the heat source is to heat your house, or if overheating is a concern.

Not extremely hot. I'm not exactly sure what to compare it to for an example...hmm, maybe say you had like fifty 60 watt bulbs in a particular room in your house - in lamps that were placed on the floor. What could you cover those lamps with to make the heat undetectable by infrared?

Thanks for the reply btw.
 

1. What is infrared radiation?

Infrared radiation is a type of electromagnetic radiation that has longer wavelengths than visible light. It is invisible to the human eye, but can be detected by specialized equipment.

2. How is infrared radiation used in everyday life?

Infrared radiation is used in a variety of ways, such as in thermal imaging cameras, remote controls, and heating systems. It is also used in scientific research and medical imaging.

3. Is infrared radiation harmful to humans?

Infrared radiation is generally considered to be safe for humans, as it does not have enough energy to cause damage to our cells. However, prolonged exposure to high levels of infrared radiation can cause skin burns.

4. How is infrared radiation related to temperature?

Infrared radiation is emitted by all objects with a temperature above absolute zero. The amount of infrared radiation emitted by an object increases as its temperature increases.

5. Can infrared radiation be reflected or absorbed?

Yes, infrared radiation can be reflected or absorbed by different materials. For example, objects with a dark, matte surface tend to absorb more infrared radiation than objects with a light, shiny surface which reflect more of it.
