Similarly one may ask, how are waves used in remote controls?
Remote controls work through sending electro magnetic waves through the air that the TV can pick up. The control sends out infrared waves which is a type of electromagnetic radiation, which includes radio, gamma, and micro waves, as well as all visible light.
One may also ask, what frequency do TV remotes use? TVs and radios typically have Infrared (IR) remote controls. Most cars now have a radio frequency (RF) remote key fob. Wireless keyboards and mice use RF links at 27Mhz or 2.4Ghz. Cordless phones use 900Mhz, 2.4Ghz, and now 5.8Ghz.
In respect to this, how do TV remotes use infrared waves?
An IR remote (also called a transmitter) uses light to carry signals from the remote to the device it controls. It emits pulses of invisible infrared light that correspond to specific binary codes. These codes represent commands, such as power on, volume up, or channel down.
How do you control radio waves?
Thin amounts of plastic wrap, wax paper, cotton and rubber are not likely to interfere with radio waves. However, aluminum foil, and other electrically conductive metals such as copper, can reflect and absorb the radio waves and consequently interferes with their transmission.
