what happens when infrared radiation falls on window pane?

some is reflected by the glass, and some passes straight through.  A tiny part will go towards heating up the glass itself, as it is absorbed during its transition throught the glass.

Just what are you doing with radio active material on your screen? Inquiring minds want to know, yes, really the want to know.  Anyway, if you are talking about the emitions that eminate from your CRT monitor, check with the manufacture of the monitor. I am sure that you will find that you are safe, however, if you still believe that there's radiation will harm you coming from your monitor, then i would suggest wrapping your head in aluminum foil, don't use tin foil it only intesifies the beams, and wear sunglasses of at least 80% darkness You will find that should protect you, oh, yes, insure that you secure a radiation vest, yoiu know the kind that X-Ray techs wear when they take your x-rays (try e-bay).  Additionally, you can find like minded individuals on the web (try paranoids and conspirist dot com).  If you are still worried and scared you can always turn it off, and sell it or destroy it so that it doesn't hurt anyone eles.

1) Generally, rays of the sun which is called radiation lay between 400 nm (nano meter) to 700 nm.\n2) Below 400 nm is called ultra-violet and above 700 nm is called Infra-red.\n3) Both are invisible to the human naked eye.\n4)Infrared radiation is used to obtain pictures of distant objects and the detection of infrared radiation is used by astronomers to observe stars and nebulae.

Not only does it emit heat but it also emits infra-red radiation...

Infrared is light that has a wavelength outside the bottom of the visible spectrum--it is essentially the "colour" that occurs before red (the lowest visible wavelength).\n\nThe invisible "light" that occurs at the top of the visible spectrum is ultraviolet.\n\nBoth of them can't be seen with the naked eye, but can alter the way the eyes perceive the other--visible--colours.

It really depends on the motion sensor. There are two types, active and passive. Active sensors include the sensors that open grocery store doors (these send out microwave radio energy then wait for it to bounce back), also alarms that emit beams of light (if the beam is broken the change in light is detected). Active sensors basically send something out into the environment and receive the changes. The motion sensor in most alarm systems are considered passive dectectors because they don't emit anything, but detect changes in energy such as infrared energy. These are usually set to detect small changes in the temperature of the human body. One cool experiment is if you stand behind a window, the motion sensors won't "see" you! This is because glass isn't a good conductor of infrared energy. Either way, these devices are interesting inventions!

I would say no.  If you are talking about getting the proper rays to get vitamin D among other things my understanding is that you need the ULTRAVIOLET RAYS for this.  Infrared rays create heat but ultraviolet rays do the chemical reaction thing - so to speak.  \nhttp://www.freewebs.com/eclecticstuff\nUltraviolet rays don't readily pass through glass.  Especially NOT polarized glass like in UV sunglasses.

Highlight the column to the right of where you want the freeze, then go under Window and freeze panes

Anything warmer than the air temperature will be affected\n\nMeaning more heat will be lost from the warm object if there is  wind. The wind moves the lost heat away from the object.

It may be over-heating

What you perceive as transparent glass transmits visible light because none of the differences in energy level bands match the energy of visible light. If they did, light would be absorbed by the material as electrons were excited into higher energy levels. Clear glass is still opaque in other frequencies, such as infrared.

unless you break a window

my laptop manufacturer recomends window cleaner and a lint free cloth.  that's what I use and it works without harm to the screen.

If the energy of the light does not correspond to the difference in two energy levels in the atoms it hits, the light will pass through. The vast majority of photons are passed through the glass this way. The rest are reflected at the surface or absorbed and dispersed.

What you want is an IR blocking filter. An optical supply house like Melles Griot , Reynard, or Edmund can supply you with one.  Depending on the intensity of the radiation, you may be better off using a cold mirror or hot mirror. These are dichroic mirrors that pass infrared and reflect visible light, or vice versa. They can be used where a blocking filter might get too hot from the radiation absorbed. \n\nSchott glasses KG1 through KG5 are some available IR blocking filters.

this may mean that its a close botton if its on the outer side of the window but if its in the inside well most likely means that there is and image that is online that the pc cant reach\n\nKFH king

If you tint it, it adds to the heat being absorbed to the glass.  Dark things absorb more light, light colors reflect more.  So the window should then start becoming hotter than before and hence why you should start seeing it crack now.  Also is the window facing east, it would explain the time of day it is cracking.  Now the window will not only heat to a high temperature, it will do it faster from the however cold it will have gotten overnight.
