Where I live they recently re-painted I see alot of Yellow with silver caps and a handful off all red hydrants,I know this has something to do with P.S.I but anything else?
It can as it is part of the Electromagnetic Spectrum. Electromagnetic radiation from space is unable to reach the surface of the Earth except at a very few wavelengths, such as the visible spectrum, radio frequencies, and some ultraviolet wavelengths. Astronomers can get above enough of the Earth's atmosphere to observe at some infrared wavelengths from mountain tops or by flying their telescopes in an aircraft. Experiments can also be taken up to altitudes as high as 35 km by balloons which can operate for months. Rocket flights can take instruments all the way above the Earth's atmosphere for just a few minutes before they fall back to Earth, but a great many important first results in astronomy and astrophysics came from just those few minutes of observations. For long-term observations, however, it is best to have your detector on an orbiting satellite and get above it all!
I agree with Rebecca. My fiance needs time to himself every so often, but I don't have any friends. He also hates to tell me to get out of the house for a day because he feels like he's being mean about it. One thing you can do is talk to her about it nicely. Tell her you need some time to yourself sometimes. Or, you can do the unnecessary and find stuff to keep her busy. Good luck!
IR radiation, like all other EM radiation, can travel through a vacuum.
All frequencies radiation can pass through space. Get your facts straight.
Infrared radiation is part of the electromagnetic spectrum, which visible light is a part of. So you're exposed to it constantly; our skin protects us from any hazardous effects of normal, cosmic radiation, which only becomes a concern when one is either up high in the stratosphere, or outside of its confines entirely. Down on the ground, it isn't really an issue. You should be more worried about nuclear radiation, which is isotopic, and can destabilize molecular structures far more aggressively.
