experiment where you shine a flashlight at a tv with your hand on it?
have you ever heard of this experiment? if so what is supposed to happen?
Try it for yourself and see what happens! (=
PROCEDURE
1. Clear all obstructions between you and the television set. Darken the room as much as possible. Stand about 3 meters (10′) away from the set and test your remote control unit to make sure it is functioning properly. Test your flashlight by shining it against the dark television screen.
2. Have a friend stand about halfway between you and the television, directly in front of the screen. Try turning on the television using the remote control. Then try shining the flashlight onto the television screen. Observe what happens in each trial. Have your friend move around and notice how both “light” beams behave.
3. Have your friend blow some cornstarch or baby powder in the air between you and the television and attempt to turn on the television through the dust. Repeat, using the flashlight, and observe what happens when you aim it at the screen.
4. Place the glass of water directly in front of the remote control unit and try to turn on the television. Now shine the flashlight through it. Note what happens in each case.
5. Hold the remote control in your right hand and place your left hand at several distances and angles relative to the remote control. Determine the conditions under which your hand motion prevents the signal from reaching the television.
The purpose of this experiment is to see your remote control infrared radiation.
