They use electromagnetic waves. cellphones use radio waves while electric and microwave ovens use infrared and/or microwaves
Each X-ray photon carries more energy than an infrared photon does. But it's still very easy to shine an infrared beam that has far more energy than an X-ray beam. Simply use an infrared source that radiates more photons than the X-ray source does.
the light you use to heat food is an examle of a infrared wave.
you can use infrared photographs catch amazing picture
Microwaves are close to infrared so much of the technology is similar.
Infrared rays are used in television remote controls
use the sun ****
you use them for television and for fm and am
infrared rays
Infrared light is heat. That would work best. But UV rays would too because they cause sunburns and are used in tanning booths
the uses of infrared rays:Doctors use infrared lamps to treat skin diseases and relieve the pain of sore muscles. In these treatments, the infrared rays pass through the patient's skin and produce heat.Scientific advances pertaining to infrared have allowed buildings to keep cool even in the summer. Gold transparent films in the windows of large office buildings reflect infrared and help to keep temperatures cool.Photographers use film that is sensitive to infrared rays to take pictures in places where there is no visible light. Burglar alarms also use infrared.Infrared is used extensively in specially-designed ovens for drying painted and enameled surfaces, leather, metals, papers and textiles.
Infrared radiation (most common form of terrestrial heat radiation.)

The heating bulbs in bathrooms use infrared light to heat.
Infrared rays are the only way that heat can travel through the vacuum of space, and as such, are the means by which the Sun is able to warm the Earth. Without infrared rays, the Earth would be far too cold for life. Additionally, infrared is sometimes used as a means of heating things, such as in the cooking of food, along with other forms of heat transfer such as conduction and convection. Because some infrared radiation is given off by any object with any warmth, special devices can allow people to see in complete darkness by detecting infrared radiation, and then converting it to visible light on a screen (ie, night vision goggles). Some animals, such as pit vipers, have special senses specifically for infrared radiation, allowing them to detect warm blooded prey.
