Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.

What is the difference between sound waves and radio waves?

The differences between radio waves and sound waves are as follows:Radio waves can be considered to be made of waves as well as particles. Sound is only a wave. It does not show particle nature.Radio waves are electromagnetic waves while sound waves are mechanical waves.Radio waves are transverse while sound waves are longitudinal.Radio waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.The speed of radio waves in a medium is constant. The speed of sound waves can change.In sound waves, the particles of the medium actually oscillate. In a radio wave, the electric and magnetic vectors oscillate.Radio waves can be polarized, but sound waves cannot.Radio waves travel much faster than sound waves. The speed of radio waves is a physical constant. Its value is exactly 299,792,458 metres per second in vacuuum. The speed of sound is 343 metres per second in dry air at 20°C.Radio waves are electromagnetic radiation and travel at the speed of light. Sound waves are mechanical vibrations in a medium.


Do radio waves travel at the speed of sound at the speed of light or at some speed in between?

'Radio' waves are physically and electrically identical to light waves except for their frequency (wavelength), and they travel at the same speed as light does.


Does radio wave travel faster than sound wave?

Light waves and radio waves travel faster then sound waves. It has been know for thousands of years that you can see something happen in the distance before you hear it happen. Radio waves and light waves are both electromagnetic waves and both travel at the speed of light. The speed of a Radio wave is same as of Light and it is 3X108 meter /sec while sound travels with speed of 300 m/sec.


Why do radio waves travel faster than the sound wave?

Radio waves are just low frequency light waves. They travel at the speed of light, much faster than sound waves which are just changes in pressure traveling in waves


Do radio waves need medium to travel?

no they do not, they can travel through vacuums and do not need particles to travel as sound waves do. radio waves are transverse waves whereas sound waves are not


Do radio waves travel faster than sound waves?

Light waves and radio waves travel faster then sound waves. It has been know for thousands of years that you can see something happen in the distance before you hear it happen. Radio waves and light waves are both electromagnetic waves and both travel at the speed of light. The speed of a Radio wave is same as of Light and it is 3X108 meter /sec while sound travels with speed of 300 m/sec. In both cases, if the wave travels through a medium, the speed of the wave is reduced by the index of refraction. There is no normal medium where the speed of light could be altered to make it a million times slower or sound sufficiently faster to allow any electromagnetic wave travel more slowly than sound.


Why can you assume radio waves travel at the same speed as light?

Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.


What travels faster the sound from a person or a radio waves sent to a radio?

Sound travels at the speed of sound, whereas radio waves travel at the speed of light. The speed of radio waves is much faster than the speed of sound. If you're seated high in the stands at a baseball game, watching it on the field and listening to the game on the radio at the same time, it's quite common to hear the crack of the bat on the radio before you hear it straight from Home Plate.


Which travels faster-radio waves or sound waves?

Radio waves travel roughly 874 thousand times faster than sound waves travel in air.


Why can radio waves travel through space but sound waves can not?

Radio waves travel through empty space because they are electromagnetic waves, whereas sound is a wave that must travel through air.


Are radio waves sound waves?

Radio waves can carry sound signals. But by definition radio waves are not sound waves. Radio waves can travel in a vacuum, but sound waves need a physical medium.To explain the apparent contradiction, the sound wave is converted to an electrical signal version that is then used to modulate the radio signal.No it is not


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.


Do sound waves travel at the speed of light?

No, sound waves travel much slower in the medium air.


How fast do radio waves travel?

They travel at the speed of light. Radio waves are a form of light, but a much lower frequency than we can see with our eyes. Also Einstiens theory states that nothing can travel the speed of light however all waves travel the same speed making radio waves travel the speed of light. Hope this helps from scottadroid :D


Speed of radio waves?

Like all other electromagnetic waves, they travel at the speed of light.


What is the difference between radio waves a light waves?

Light waves are visible - radio waves are not. But they travel at exactly the same speed.


Radio waves travelthough space at what speed?

In a vacuum radio waves travel at the speed of light, about 186,000 miles per second.


What speed do radio waves travel in air?

They are electromagnetic waves, so they travel at the speed of light, 3.0 x 108m/s.


Which waves travel at the Speed of light?

All electromagnetic waves, including radio.


Can you start a sentence with a sound?

Sound waves travel through the air to my radio.


What is the speed of gps signals?

GPS signals are radio waves. Radio waves travel at the speed of light. Speed of light is about 186,000 miles per second.


How do light and radio waves travel?

Both waves travel with the speed of 3*108 m/s in vacuum. Both have electric and magnetic filed perpendicular to each other as they travel. Both waves does not require and medium to propagate like sound waves.


How fast are ultrasonic sound waves?

Ultrasonic sound waves travel at the same speed as lower frequency sound waves. The medium determines the speed at which a sound wave, which is mechanical energy, can travel. Sound waves travel faster in liquids than in a gas (like air), and travel faster still in solids. The speed at which a sound wave travels is generally independent of the frequency of that sound. Use the link below for more information.



How fast radio waves travel?

At c, the speed of light.
