Thanks for the feedback!
They most use infa red but they use wireless for the more recent technology.
The radio wave I believe.
plastic software and mostly circuits. also some springs
In ordinary remote controls for devices such as televisions & DVD players, infra red light is used (naked to the human eye).
A few remotes use radio frequencies. Garage door openers. Car entry. Most home system units and some car entry use infrared light. Still electromagnetic.
infrared radiation is used in tv remotes
The type of waves used in tv remotes are IR waves, otherwise known as infrared waves.
Although not true of every system, the vast majority of remotes for TVs and other home AV equipment use infrared radiation to transmit information. Infrared radiation is very …similar to visible light, but of a shorter wavelength, so our eyes can't see it. it is however of a higher wavelength than radio waves on the electromagnetic spectrum, illustrated at the link
It depends what you mean by TV wave. If you mean the transmission of television signals, then yes. An electrical signal can be transmitted from about 10kHz, so fits into the l…ow end of the electromagnetic spectrum. The frequency for TV carrier signals will vary around the world, but they're typically VHF and UHF, so from 30MHz to 3GHz. Of course, digital systems and satellite distribution mean higher frequencies - in the microwave spectrum (higher frequency than light).
Radio waves. A bit higher in frequency than "radio", but not much.
Remote controls use both infrared and radio frequency technologies. Your typical TV remote uses infrared and your typical car remote uses RF.
UV waves are caused by the electromagnetic spectrum that imitates the sun. It is used in heat lamps and sensing devices.
