Who can see the infra red rays?
microorganism
What animal can see uv rays and infra-red light?
Goldfish
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.
Can you see body nude beneath clothes with the help of infra red rays?
No.
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.
Can only some snakes see infra red?
All snakes can see Infared, its used for hunting.
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 and white mode. The infra red floodlight, lights up the subject, at close range and reflects back for the camera to see. The infra red capabilities of a digital camera can be checked yourself. Look at the front of an infra red remote control and push a button. You won't see anything. Now use your digital camera or phone camera. Point the remote control at the camera and press a button. You will now see the infra red LED on the remote flash white!
What type of waves are used in night vision?
Infra red radiation is the best. Usually living bodies would emit IR radiations which could be seen through IR spectroscope or telescope. Though IR are not visible to our eyes those can be recorded on suitable films.
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.
