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.
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.
