What is infra red spectra stretching?
In molecules, there are bonds. When they are exposed to infra-red radiation, different bonds absorb the infra-red radiation at different wavelengths. In the observed spectrum, there are "bond stretches", where the observed intensity of certain wavelengths drops due to the absorption. By comparing these "stretches" with a data-booklet, you can see which bonds the molecules have. This is called Infra-red Spectroscopy. ...

Why do you see a white spot on the camera-display when you make a photo of a remote-control?
Because remote controls use infra red light to communicate with the TV, stereo or what ever the remote is for. Infra red is a type of light we cannot see with our eyes, but cameras and video cameras turn infra red into visible light. ...

How do night vision works?
The night vision of domestic video cameras work by infra red. All video cameras, whether using CCD or vidicon tubes, are sensitive to the invisible spectrum of infra red. This feature is used on domestic cameras by using a high power, infra red emitting LED, on the front of the camera, to act as a floodlight. No one can see it, but the camera can. When switching it on, it also increases the sensitivity of the CCD and as a result switches to black...
What type of waves are used in night vision?
The infra red waves are used in night vision. If you throw infra red light on the person, he will not be able to see the same. You can see the infra red waves through special devise, meant for to detect the same. Hot objects tend to emit more infra red waves. It is worth interesting to know that some of the insects and probably some other animals can 'see' the infra red waves with naked eyes. ...

Are you able to see an object when it emits infrared radiation?
Infra red radiations are invisible to our vision. Only red to violet are visible. But when the object emitting infra red radiations is in a dark place, then the object too cannot be seen. ...

What happens when infrared waves enter a parked car?
Nothing... Infra-red is everywhere and cars are largely unaffected, your TV remote emits infra-red waves - point one at your car and see what happens. ...

Can night vision goggles see through fog?
It depends on whether the night vision goggles are image intensifiers or the type that are sensitive to infra red. Only the infra red type can see warm objects through fog. Image intensifiers will not be able to see through fog at all. ...

Infrared radiation and visible radiation?
Visible radiation (a.k.a. light) is the wavelengths we can see. Infrared radiation lies down below the red end of the spectrum that we can see, hence infra red. But we can make device that both generate and detect infra red radiation. Your TV control works this way. ...
Asked in Physics
What are two light energy waves that you can't see?
The two ligh energy waves that you can't see are ultra-violet (UV), and infra-red (IR). Ultra-violet light waves are measured at 380nm and below, infra-red light waves are 750nm and above. Normal light that you can see resides between these two regions. ...
Asked in Physics
What is the difference between infra-red and light?
Infra-red simply means less than red (referring to its place in the spectrum) and it is a wavelength that we cannot see. Similarly, ultra-violet means greater than violet and it is at the other end of the light spectrum, again of a wavelength that we cannot see. There are a lot of wavelengths of electro-magnetic radiation (as these are called) that we cannot see, radio waves being some of them. ...

Is it safe to see the solar eclipse in the reflection of water?
No because the ultra violet and the infra red will still reflect of the water to your eye ...
What is the tiny bulb on a remote remote control that sends information to a TV called?
The "bulb" is an infra-red light emitting diode, normally abbreviated to infra-red LED or IR-LED. It sends a stream of light pulses carrying information to the receiver or sensor on a television. Although it uses light, it is not a part of the spectrum that we can see, so we do not see it operating. ...

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? ...
