Difference between radio wave and sound wave?

Answer 1

The frequency of all electrical waves is measured in cycles per second or Hertz, sound waves or audio is the lower range of the spectrum from one Hz to about ten Kilo Hz where the frequency is to high for human or animal hearing that is where radio waves or radio frequency start up to many Giga Hz where the different light frequencies start like white light, infra red, ultra violet and X-ray ETC.

Answer 2

Radio waves are a type of electromagnetic wave that can travel through a vacuum, while sound waves are mechanical vibrations that require a medium, like air or water, to travel through. Radio waves have much longer wavelengths and higher frequencies compared to sound waves, which makes them suitable for long-distance communication such as broadcasting.

Answer 3

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.

Answer 4

With acoustic waves (or sound waves) something - like a whistle, drum, rock band, baby ... etc. has caused differences in the pressure of the material that the wave is traveling through. It's the rate at which these pressure variation occur which make one sound a higher pitch (frequency) than another. These are longitudinal waves, that is the change in pressure occurs along the direction of travel of the wave.

Electromagnetic waves, including radio waves, light, etc., are the result of variations in electric and magnetic fields, not air movement. These waves are transverse waves, the change in electric and magnetic fields occurs transverse or perpendicular to the direction of travel of the wave.

We commonly experience acoustic waves in the air and it is acoustic waves that the ear can detect, however acoustic waves can travel through all kinds of materials. That's why you can hear under water or in the old western movies someone would put their ear to the ground or to the rail of a railroad.

Acoustic waves generally travel a lot slower than electromagnetic waves, but the speed of each is dependent on the characteristics of the medium that it is traveling through. See the related questions for information.

Answer 5

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

Answer 6

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.

Answer 7

Sound wave is a mechanical wave which badly needs a material medium to get propagated

But radio waves are electromagntic waves which could even travel through vacuum

Sound wave has velocity of the order of meter just 330 m/s

But radio wave travels at incredible speed 300,000,000 m/s

Answer 8

Radiowaves meduim- elecromagnetic feilds

soundwaves medium- matter

speed of sound in air- 330m/s

speed of light in vaccum- 3*10^8 m/s

radiowaves- transverse

soundwaves- longitudanal

Answer 9

Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
