Radio 'waves'.
Radio waves. A bit higher in frequency than "radio", but not much.
infratered radiation
electromagnetic waves
An electromagnetic wave does not need a medium through which to travel. This includes light, radio, TV, X-4ay, etc. The wave contains its own medium which is a photon.
Light waves do, but sound waves cannot, because in space is no medium to carry the vibration. Radio, TV and others can travel in space also.
The radio wave I believe.

Electromagnetic waves can travel in a vacuum. Radiowaves, which are used in television signals, are one part of the electromagnetic spectrum.

Infrared (IR) is a type of wave on the Electromagnetic Spectrum. Infrared is also a technology which is most popularly used in remotes. TV remotes use a IR blaster to send IR signals to an IR receiver on the television.
It seems so. Any way it is electromagnetic wave which could be modulated with digital pulses.
A radio wave is an electromagnetic wave. It's a form of electromagnetic radiation.The term "radio" is the name given to a part of the spectrum of electromagnetic waves that is used for radio and television broadcasting, mobile phones, terrestrial and satellite wireless communications networks, etc.The whole wide spectrum of electromagnetic waves has frequencies (and wavelengths) ranging from "audio" to "radio" to "infrared" to "visual light" to "X-Rays", and beyond to "gamma rays" at the very top end of the spectrum.
No. We get electromagnetic waves from the sun. We can see stars and sun even though there is a virtual vacuum between us. Electromagnetic radiation or electromagnetic waves includes the radio and television signals that we can get from space satellites.Sound is not an electromagnetic wave, it needs a medium.
An X-ray is a high frequency (high energy) electromagnetic wave. It is much higher in frequency than any broadcast wave. The only electromagnetic radiation with higher frequency (shorter wavelength) than the X-ray is the gamma ray.
Radio wave brings the information into the TV set from which the sound and pictureare reconstructed.Light wave carries the picture ("video") information from the screen to your eyes.
