What else can I help you with?
What kind do wavelength do television signals have?
Long
Why does television signals travel through a vacuum?
television signals are communication signals, which can either be radio or microwave signals. These are both part of the electromagnetic spectrum. In the spectrum all the different signal types have some similar properties, including being able to travel through a vacuum, usually because they have a strong enough frequency and wavelength, and they don't need to travel in particles but waves :)
What waves that have the longest wavelength and are used to carry audio and picture signals over long distances are known as?
They are called as radio waves. They have got the speed of light. The wave length of the radio wave may be up to few kilometers.
What does a TV card do?
A TV card is a kind of television tuner that allows television signals to be received by a computer. TV Tuners also function as video capture cards .
What is the wavelength of a tv remote?
The peak wavelength of the IR diode used in TV remotes are usually around 940 nanometers.
Television signals are converted into light signals by?
Laser Diode. photo diode
Can a wireless network effect tv reception?
Assuming you are talking about over-the-air television and you live in the United States, then no, it's not possible. Wifi networks use a spectrum of radio frequency much higher than the bands designated by the US Government for UHF television (and most TV networks have signals in the VHF band, which is even lower). Interference is a result of multiple signals competing on the same wavelength, or very near it, and that is simply not possible for over-the-air television, as it operates at a much lower frequency.
Did eygptians watch TV?
Egyptians, like the rest of the world, (Mexicans, Italians, Japanese, etc) receive over the air TV signals, satellite TV signals, and cable TV signals. So the answer to this astoundingly stupid question is YES!
How are signals relayed?
Cable Television
Do wind turbines affect radio and television signals?
If placed in the wrong location, wind turbines can affect radio and television signals.
What kind of energy does a TV set changes?
A TV set converts electrical energy into light and sound energy to display images and emit sound. It does this through the process of converting electrical signals into visual and auditory output.
How does a Television works by transforming electrical energy into what other kind of energy?
A television works by transforming electrical energy into light (for the display panel) and sound (for the speakers), as well as electromagnetic waves for receiving and displaying broadcast signals.
