There are a number of different types of remote controls. As regards those used most around the home, we find that infrared light is the most commonly applied one. Infrared light is light just below the visible spectrum. TV's, DVD players and audio systems usually use this kind of device. They're very common, but there are other types of remote controls in common usage.
Remote controls for garage doors, gates and the like use radio waves in the 300 MHz to 400 MHz range. We also see radio waves on frequencies just above 70 MHz used for many remote control (RC) model aircraft and vehicles. Again we see radio waves used in most remote controls for Video Games. But these operate in the microwave band somewhere around 2.4 GHz, in case you wish to differentiate microwaves from "regular" or lower frequency radio waves.

∙ 14y agoA few remotes use radio frequencies. Garage door openers. Car entry. Most home system units and some car entry use infrared light. Still electromagnetic.

What type of em radiation does a car key use?
Car keys that have remote controls for locking and unlocking the car use radio wave band electromagnetic radiation as their carrier, typically in the hundreds of megahertz. E.g. in Europe, most car keyfobs use 433 MHz. Some keyfobs may also use Infrared radiation as a carrier, similar to TV remote controls. In both cases a code is transmitted to command the car to unlock or lock. In code-hopping systems, this code changes each time the keyfob is used to stop criminals from capturing the code and retransmitting it to unlock a veichle.

How has the remote control changed over time?
Wired remote control devices date to the twenties and are used to control railroad and subway switches and signals. Indeed Remote-Control was for a time a patented trade phrase for Union Switch and Signals systems.
Which type of remote-sensing system records electromagnetic radiation using a satellite-mounted sensor?
a compass

Is remote control the same as radio control?
Not usually, remote control may be via wires, hydraulic, radio waves or smoke signals, Radio control refers specificaly to items controlled by radio.
What are the main uses of IR radiation?
Heat lamps and remote control devices.
Why would a mapmaker use active remote sensing instead of passive remote sensing?
Active remote sensing uses its own electromagnetic radiation and use microwaves. It maps areas hard to map.
What is a RC transmitter used for?
According to information RC transmitters relates to radio signals for a remote control device. The radio singles are transmitted to any device that has been designed to work by remote control such as toy helicopters and remote control cars to name just a couple of remote control types of items.
Is infrared radiation used in remote controls for tv?
It seems so. Any way it is electromagnetic wave which could be modulated with digital pulses.
