I was just thinking! How does a remote control work? Im talking about the infrared part of it as used on most TV!
For example:
Everyone knows that you do not have to point your TV remote at the TV to change the channel! This is because the Beem bounces off the walls for a few seonds until it hits your TV's IR reciever!
The question i am asking is:
Why dont the IR beem bounce back off your TV's IR reciever, hit another wall then bounce back towards your TV to change the channel again?
How come it bounces off the walls, but not the TV?
If id did do that, your TV would change channels twice!
Anyone know anything about this?
