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.
miniwaves. They use this so it can fit into the televisions.
The type of waves used in tv remotes are IR waves, otherwise known as infrared waves.
Communications Satellites ************************ Electro-magnetic waves. Carrier 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
Initially I had no idea whether people in Guatemala use a TV or Radio or not. Given that there's still a lot of poverty there: It shows that: about 10% own a TV about …6% own a radio only 1% own a computer only about 0.6% have Internet access. Guatemala's Literacy rate = 63%, which is remarkably high for a poor nation; compare that to parts of Los Angeles, Calif, where the literacy rate is quite low, I would guess it's about 40% to 50%, because of all the immigrants in L.A.
Radio waves are generated and modulated with the transmitted information at the transmitting station and radiated by its antenna. These radio waves are picked up by the receiv…er antenna, filtered from all the other transmitted signals, detected and demodulated by the receiver to recover the transmitted information.
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).
299,792,458 meters per second ( the same speed of light) (Note that the radio wave has no choice of where it's headed, and no choice of its speed. Its speed remains constan…t as long as it continues moving through the same stuff.)
They are all radio waves with frequencies lower than visible light.
