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.


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!

Do flies see in infra red?

Flies do not see in infrared. They have compound eyes that are sensitive to different wavelengths of light, but they primarily rely on visible light for their vision.


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.


Where is infra red radiation emmited from?

Hot objects emit infra-red radiation. E.g. the human body.


Is night vision UV vision?

No. Night Vision equipment uses infra-red (IR) light, wavelengths of light longer (lower frequency) than visible light. Infra="below", red, or light below red light in the spectrum. UV stands for ultra (above)-violet, light that is above the violet light spectrum, so higher frequency=shorter wavelength.
