infrared radiation:)
you feel the heat because electromagnetic waves carry energy so objects that absorb electromagnetic radiation receive energy.
Solar flares emit electromagnetic waves.The electromagnetic wave interrupted cellular phone communications.Satellites can be damaged by electromagnetic waves.
Toasters and incandescent (old fashioned) light bulbs are very similar devices.Both of them use electric current passing through a wire to make the wire emitheat and light. In the light bulb, we use the light, and the heat is a nuisance.In the toaster, we use the heat, and we don't much care about the light.
There are two types of smoke detectors:Alpha particle - these do not use electromagnetic wavesPhotoelectric - these use a beam of either visible lightor near infrared electromagnetic waves

Radio waves, sounds waves arn't electromagnetic waves.

Electromagnetic waves
WiFi uses electromagnetic waves in the microwave band, around 2.4 GHz or 5 GHz.

Radio waves ARE electromagnetic waves.
