Tip & How-To about Televison & Video
Infrared is an electromagnetic wave that is just below the visible sprectrum. The lowest is RED and anything below that would be invisible to the naked eye. Try this experiment. Open up your pc cam. Now point the TV remote straight at the cam and you should see the the pulsating infrared on your computer. If your remote is not working this experiment will at least tell you that the remote is giving off infrared pulse or not.
