-- The speed of radio in air is the same as the speed of light in air.
-- That in turn depends on the temperature, pressure, and humidity of the air.
-- At 'STP' (standard temperature and pressure) the refractive index of air
is listed as 1.00027.
So the speed of light/radio would be 99.972% of the speed in vacuum.
That's 299,711,536 meters per second, down from 299,792,458 in space.
What else can I help you with?
Can a radio signal be heard years after being sent?
Yes, if you're far enough away from its source. (Radio travels at the speed of light.)
The speed of radio waves is 3 x 108 ms in air. Radio station KRLD transmits at 1080 kHz. What is the wavelength of the signal coming from the KRLD tower?
Wavelength = (speed) divided by (frequency)= (3 x 108) / (1.08 x 106)= 277.8 meters (rounded)Happy listening in Dallas.
Can radio waves pass through clouds?
Clouds interfere with radio signals because the density of the cloud can cause static with the radio signal. The air can also interfere with the signal.
How can you get radio signal from space on your cmputor?
You can get a radio signal from space on your computer using SETI.
What radio channel is radio Disney in Rochester NY?
There is no current over-the-air station airing Radio Disney programming in Rochester, NY...and there have been no plans announced to bring it to Rochester in the immediate future. The closest Radio Disney signal is WOLF (1490 AM) in Syracuse, and its 1000 watt signal is not strong enough to reach Rochester.UPDATE: WOLF (1490 AM) is now off the air. BTW As of this year, Radio Disney will go exclusively digital. That means it will air on livestream, Tunein, and XM.
What is the speed of a satellite signal?
The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.
What does propogate faster a sound signal or a radio signal?
Radio signals propagate faster than sound signals. Speed of light (radio) is about 186,000 mps Speed of sound is about 1100 fps (0.5 mps).
What travel faster a radio signal or sound in air explain?
Radio signals travel at (essentially) the speed of light, as they are electromagnetic waves like light. Sound waves travel at roughly 1200 km/h. Now you have enough information to answer your own question.
Which travels faster a radio signal or a sound?
Radio signal being an electromagnetic wave does not need even a material medium. It has velocity so incredible which equals to that of light as 300,000 km per second. But sound is a mechanical wave which needs badly a material medium and its speed is just 350 m/s in air and some how higher in solids
Can a radio signal be heard years after being sent?
Yes, if you're far enough away from its source. (Radio travels at the speed of light.)
What sort of signal in GPS travel at the speed of light?
The GPS system is a network of devices that communicate by radio. Radio signals are electromagnetic radiation, just as light is, and they travel at the same speed as light does.
Who travel faster a radio signal or light in space?
They are the same physical phenomenon, with the same identical speed.
The speed of radio waves is 3 x 108 ms in air. Radio station KRLD transmits at 1080 kHz. What is the wavelength of the signal coming from the KRLD tower?
Wavelength = (speed) divided by (frequency)= (3 x 108) / (1.08 x 106)= 277.8 meters (rounded)Happy listening in Dallas.
Which travels faster an digital video signal or audio signal?
Depends. If they're all encoded for transfer by electronic means(radio, fiber, wire) they'll all travel at the same speed. But if you by audio signal mean sound in the air, then sound travels at about 700 miles an hour. A digital signal - electrical/optical - travels at the speed of light (186,282 miles per second) down a fiber network.
How radio signal works?
Your radio signal works by using its signal to go to a tower and back to your radio (Via antenna).
What type of energy transformation does a radio signal have?
The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
What are the disadvantage of ultrasonic wave communicaton?
Communication is at speed of sound. Signal attenuation. Noise of signal travelling through air.
