Why does tv use radio waves?
Low frequency electromagnetic waves.
creates a alternating current at the same frequency. :)
by changing the amplitude or frequency of the radio waves.
The radio wave I believe.
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.
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
how are radio waves be used- well they are used by sound waves like as in u can hear sond waves but radio waves is where you are in the car and u are listening for instance ca…pital fm that is radio waves Hope It Helped Hennddyyyy:) :D
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).
Television works with electromagnetic waves both for audio and video, on different configurations and separated circuits.
They are all radio waves with frequencies lower than visible light.
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.
