What kind of signals can travel without air?

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!)
How fast are microwaves signals in air?
Microwave signals travel at the speed of light in air, which is approximately 299,792,458 meters per second. This high speed allows microwave signals to transmit data rapidly over long distances.
Does air travel through solids liquids and gases?
Air can travel through some kinds of solids, if they are porous. Otherwise it can't. It can travel through liquids in the form of bubbles. It does not exactly travel through gases so much as mix with them.
Why are thedifferent gases in air important to life on earth?
Without different gases there will be no air, if there is air, how can oxygen travel?
Can sound travel through other kinds of material than air if so does it travel differently?
Sound can travel through all matter. The speed at which it travels depends on the density of the material.
Can a permanent resident travel to Mexico via air without a passport?
No.
What is the speed of radar signals?
Radar signals travel at the speed of light, which is approximately 186,282 miles per second (299,792 kilometers per second) in a vacuum. In different mediums like air or water, radar signals may travel slightly slower due to their refractive index.
Can sound travel through a room with no air?
No, sound cannot travel through a room with no air because sound waves need a medium, such as air, water, or a solid, to propagate. Without a medium, there is nothing for the sound waves to travel through.
What sound cant travel through?
sound can't travel through a vacuum. or a place without air.
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.
How do smells travel through the air and reach our noses?
Smells travel through the air as invisible molecules released from objects or substances. When we breathe in, these molecules enter our nose and bind to receptors in our nasal cavity, sending signals to our brain that we interpret as different scents.
