Physicists: What do think of computer mice that are operated by infrared? That is radiation isn't it?

Does anyone have an opinion? Sometimes my hand prickles. Has anyone experienced that?Physicists: What do think of computer mice that are operated by infrared? That is radiation isn't it?
infrared radiation is indeed one of the types of electromagnetic radiation (which by the way includes visible light, radio waves, x-rays and microwave). Such radiation is emitted by any hot body, which is why infrared is also called heat radiation sometimes. As any other type of radiation, it's danger strongly depends on the intensity, e.g. if it's strong, infrared radiation may very well fry you. The intensities which your poor mouse radiates it may never cause any prickles. What you feel is more likely because of the uncomfortable hand position.Physicists: What do think of computer mice that are operated by infrared? That is radiation isn't it?
Visible radiation is also how you see what is on a computer monitor and (assuming you are not blind) see things while walking down the street.





Prickles? I had mouse problems too with a mechanical mouse. Try switching it to the other hand for a few days. Also helps with ambidexterity.
no, it's the same infrared that is in remote controls in TV remotes that controls it. and you hand prickling? probably falling asleep from using the computer too much
