Do radio waves travel at the speed of light at the speed of sound or something in between?
speed of light
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.
How does light travel through AVACUUM?
Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.
Differences between light and sound waves?
The differences between light and sound are as follows:Light can be considered to be made of waves as well as particles. Sound is only a wave. It does not show particle nature.Light waves are electromagnetic waves while sound waves are mechanical waves.Light waves are transverse while sound waves are longitudinal.Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.The speed of light in a medium is constant. The velocity of sound waves can change.In sound waves, the particles of the medium actually oscillate. In a light wave, the electric and magnetic vectors oscillate.Light waves can be polarized, but sound waves cannot.Light waves travel much faster than sound waves. The speed of light 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.And finally, a simple one - you can see light while you can hear sound.
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

Can light travel in a vacuum?
Yes. Light waves are electromagnetic waves, which do not require a medium to travel through.Mechanical waves (such as sound) do require a medium to travel through, so sound waves cannot travel through a vacuum.Space is a vacuum. The light from the stars (including our own sun) travel across a great distance in a vacuum to get to us.The accepted speed of light is its speed in a vacuum, which is 299,792,458 m/s.
Does sound wave travel through light wave?
Sound Waves and Light Waves are different. The following are the differences I am aware of:Velocity: Light Waves travel through air and empty space at a speed of approximately 186,000 miles per second or 300,000 kilometers per second. Sound waves travel through air at the speed of approximately 1,100 feet per second or 330 meters per second.Wave Type: Sound Waves are longitudinal in nature whereas Light waves are transverse in nature.Light Waves can travel through vacuum whereas Sound cannot.Hope this helps.
Sounds need these in order to travel?
Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.
Do sound waves or light waves travel faster?
In air, light waves travel about 871 thousand times faster than sound waves.
What do you know about the speed of the 2 waves in the vacuum?
All electromagnetic waves, light, x-rays, etc travel at the same speed. Sound waves require a medium to travel thru, so they cannot travel thru a vacuum.
How can you tell from a thunderstorm that sound waves and light waves travel at different speeds?
The speed of light is 300,000 km per second where as that of sound is simply 330 m/s. So we first see the lightning and hear the thunder sound a little bit later. This confirms that both light and sound travel at different speed
