Low frequency electromagnetic waves.
by changing the amplitude or frequency of the radio waves.
The radio wave I believe.
A radio wave is an electromagnetic wave that can convey information from one point to another. This information can be modulated in many different ways. Do not confuse "rad…io wave" as applied to the electromagnetic wave with "radio wave" as applied to the specific modulation of audio information, such as music. Similarly, "tv wave" is an electromagnetic wave that is modulated to convey television information, which includes both audio and video.
Analog Television use radio waves both for audio and video. Video circuit is much more complex than audio circuit. Ancient Televisions used CRT (Cathodic rays tube) in wich a …powerful valve emmits electrons towards the inner side of the screen, and the result is the image saw by the TV watchers. The TV station broadcasts electromagnetic waves to the TV receiver which use the same radio waves to transform audio and video onto images and sound through complex electronic circuits.
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
In principle, any type of radio service can be carried on in any part of the radio spectrum. But it happens that the commercial AM radio broadcast service is situated quite …low in the spectrum ... between 0.55 and 1.7 MHz. As such, it has the longest wavelength that you're likely to run into. There are certainly services that operate at lower frequencies ... time signals to the so-called "atomic" clocks, submarine communication, legacy navigation systems etc. But of the two choices listed in the question, AM radio is by the far the lower frequency / longer wavelength.
The source is the RF current in the transmitting antenna.
AM radio waves are. This has nothing to do with the science or Physics of AM or TV. It's only the result of the frequencies where they happen to operate. In the USA, comme…rcial AM radio broadcasting takes place on frequencies between 0.55 and 1.7 MHz, whereas TV broadcasting starts at 54 MHz and goes up into the stratosphere from there. Higher frequency means shorter wavelength. Along the same lines . . . commercial FM radio broadcasting is carried on at frequencies between 88 and 108 MHz. That's higher than some TV channels and lower than others.
They travel at the same speed of light, namely: 299 792 458 m / s (Roughly 300.000 km/s or 186.000 miles per second).
Radio transmitting equipment, built and operated for the purpose of conveying information over significant distances wirelessly.
Television works with electromagnetic waves both for audio and video, on different configurations and separated circuits.
TV and radio don't need motors in order to do the job they're designed for. Almost none of them have motors, and the few that do have them, use them for functions that are… largely unrelated to the basic functions of radio and TV, like running a fan to keep the electronics cool, turning the shaft of a detent tuner, turning a directional antenna, etc.
Your landline carries the voice/data on copper wires. A mobile uses radio waves but they are a different frequency from that used to broadcast TV.
AM radio operates at 500-1500kHz, which translates to 600-200 m wavelengths. TV uses several non-contiguous frequency bands starting at 54 MHz which translates to wa…velengths of 5.556 m and below. Clearly AM radio has much longer wavelengths.
