IR is also used for short-range communications, for example between mobile phones, or for the Dolby Screentalk headset system used in some cinemas.

Is  danger cause it get really hot so it can cause fire.]]> 2017-02-27 15:15:30 UTC https://padlet.com/vegaest000/xu6opbbr575i/wish/156434344 how they are made vegaest000 https://padlet.com/vegaest000/xu6opbbr575i/wish/156434887 Infra red waves are just below visible red light in the electromagnetic spectrum ("Infra" means "below").

You probably think of Infra-red waves as heat, because they're given off by hot objects, and you can feel them as warmth on your skin.

Infra Red waves are also given off by stars, lamps, flames and anything else that's warm - including you.

The detector on this security light picks up the Infra red radiation from your body.
