Example: I have a remote controlled device, like a plane. I use the controller to tell thenplane to thrust, it thrusts. I use the controller to turn the plane, it turns. How can radio waves be used to control a device?
In: Engineering
Remote control toys work by broadcasting a signal from the controller that can be received or “heard” by the remotely controlled device. You can imagine this as if your controller was making a series of beeps when you input a command. You push the thrust up button, the controller makes the radio wave version of a “beep beep beep” through it’s antenna. The remote control device then “hears” the “beep beep beep” command through its own antenna and recognizes that as the “thrust up command”.
I’m not sure with your question but you may be asking how the controller transmits radio waves through its plastic casing. It can do that because in the same way glass is translucent to light most kinds of plastic are translucent to radio waves.
