  • It was great. Today at school I learned that infrared waves are used in remote controls.
  • how was the school?
  • Since remote controls use infrared waves, can I block the waves with an object in front of the sensor of the TV
  • Does it work with a transparent object, like a water bottle?
  • what about a piece of paper, and a metal bottle?
  • That's a good question. Why don't you test it.
  • That's exactly what I'm going to do.
  • good luck
  • My dependent variable will be If the remote control will be able to control the TV. And I don't need to get my controlled variables because they are already here, they are the TV and the remote control.
  • Daniel started planning the experiment.
  • I'm first going to get my independent variable which is a transparent plastic bottle.
  • So Daniel got the materials to the experiment, which was a plastic bottle, a metal bottle.
  • I think the remote control won't be able to control it.
  • I first need to measure the distance I'm going to be testing, so that I get right result.
  • If you put an object metal bottle in front of the TV and try to control it with the remote control from a distance of 2 meters, then the remote won’t be able to control it because as I saw in an article called answerstoall.com, any electromagnetic conductor can block infrared waves, however if you put a piece of paper or a plastic bottle in front of the TV sensor, then the remote control will be able to turn on the TV because both these materials are thin, and I the infrared waves will pass through it easily.
