The users are used for remote controls for TVs and video recorders, and physiotherapists use heat lamps to help heal sports injuries. Also, they are used night-vision goggles or infrared cameras allow us to detect the infrared waves emitting from warm objects such as humans and animals.
The danger to people from too much Infra-Red radiation is overheating.

ReplyDeleteHow does heat cameras work?
ReplyDeleteHow does infa-red light help to heal sports injuries
ReplyDeleteWhat emits infrared light?Also,there is no heading
ReplyDeleteAgree with Matthew.
ReplyDeleteI thought Infra-red can transfer information too?

More dangers
ReplyDeleteIs there any relation between the colour red from the visible spectrum and Infra-Red radiations, are they almost similar to each other like the lowest waves in the UV spectrum and the purple colour in the visible light?
ReplyDeleteSame question as Matthew and Kun Yao, how does infa-red light help to heal sports injuries?
ReplyDeleteHow are they used in night vision goggles?
