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.
Why is infra-red dangerous?
Infra-red by itself is not dangerous at all. It is around us everyday. But I am sure that you are actually curious about infra-red LASERS. If shined into the eyes, IR Lasers can burn and permanently damage the retinas.
What type of electromagnetic radiation does an infrared telescope collect?
infra-red telescope is a telescope in which you can look at everything in the waves of infra-red.
Why does light changes its colour after passing through some transparent coloured like a red coloured transparent piece of glass or any such glass or matter?
the light changes colour as some of the wavelengths are absorbed by the coloured glass
Why is infra-red radiation rather than visible light used with optic fibers?
Infra-red has less energy the visible light, and so it takes less energy to create.
What radiation is absorbed by global warming?
Infra Red Light: Global warming is associated with Infra-Red rays that the earth emits to the atmosphere, where it is absorbed by the greenhouse gases of Carbon Dioxide and water vapor.
What colour of light will be absorbed first as the sunlight enters water?
Infra-red
Do the sunbeams absorbed by the earth get radiated as a different kind of radiation?
They mostly get radiated out as Infra-red (Heat) and microwave radiation
Transfer of radiant energy is?
Mostly done by infra red EM radiation, since this is emitted by hot bodies and absorbed by bodies that receive it.
What two kinds of EM waves will NOT pass through glass?
Infra-red is the clasic example (the green house effect).
What material is the best absorber of infra-red radiation?
A black surface, indicating the surface is not reflective -- all lights are being absorbed -- visible or invisible.
Who invented the infra red waves?
Will Young invented the Infra Red Waves in 1943

When was Infra-Red - song - created?
Infra-Red - song - was created on 2006-06-19.
What is the Infra red?
vibrating molecules relase infra-red radiation (that's hot things)
How are infra red images taken?
anything warm rleases infra red waves the hotter an object is the more it releases. an inrer red camra detect infra and makes an image out of it.
What is the source of infra-red?
vibrating molecules relase infra-red radiation (that's hot things)
