What else can I help you with?
At what speed does an RF signal travel in space and how does it compare to the speed of light?
An RF signal travels at the speed of light in space, which is approximately 299,792 kilometers per second. This means that RF signals travel at the same speed as light in a vacuum.
How does RF signal travel in air?
RF signals travel through the air as electromagnetic waves. These waves consist of electric and magnetic fields that propagate through space, similar to visible light. They can travel long distances and are commonly used in wireless communication systems.
Can RF signal travel in air medium without antenna?
Yes. An antenna is only used to receive or send a signal. A RF signal travels throughout any air medium independently of the existence or not of an antenna. Of course you will need an antenna if you want to receive the signal (which has to have, by the way, more or less the same lenght of the wavelength of the RF signal), but the propagation of a electromagnetic wave doesn't need a physical support. You can see an example with the radiotelescopes. They receive signals which come from the outer space without any physical support. Electromagnetic waves (and RF signal is one kind of them) doesn't need any physical media to travel (they travel in vacuum too!)
Does noise travel up or down in a vacuum?
In a vacuum, noise does not travel because there are no particles for the sound waves to travel through.
It is possible for an electromagnetic wave to travel through a vacuum?
yes, they can travel.

Why doesn't light travel through a vacuum?
Light does travel through a vacuum.
Can gases travel through a vacuum?
No. Only light waves can travel through a vacuum.

What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
Does noise travel up or down in a vacuum?
In a vacuum, noise does not travel because there are no particles for the sound waves to travel through.
What happen when air travel through vacuum?
The vacuum becomes no longer a vacuum.
What is the one thing that cannot travel through a vacuum?
i think voice cannot travel through vacuum.
Where will sound not travel?
vacuum
Do microwave travel through vacuum?
Yes, any electromagnetic wave can travel through a vacuum.
Can light travel forever in a vacuum?
Yes, light can travel forever in a vacuum because there are no particles to absorb or scatter it.
