Radio Waves vs. Sound Waves

The main difference between Radio Waves and Sound Waves is that Radio waves are electromagnetic waves made mainly by the vibration of electrons/charges and didn't require a medium to travel within and Sound waves are mechanical waves using a medium (air, water, ground etc)

Key Differences

Radio waves made by sliding charged particles. For example electric current in a wire. Whereas things, which vibrate quite quickly make sound waves. It may have revealed by feeling your throat though speaking.
Radio waves are beam or transverse waves whereas sound waves are linear or longitudinal waves.
Radio waves travel similar light waves. They can be immersed, reflected or passed, on the other end sound waves travel within a medium. In case there is no medium then it will remain no sound.
Radio waves travel at the light speed, which is about 186,000 miles per second while Sound travels at about 1,100 feet per second (766 miles per hour).

Comparison Chart


Radio waves are a kind of electromagnetic waveform that can move when there is no medium.
Sound waves are a kind of mechanical impulsive waveform that cannot move if there is no medium.

Rate of Speed

Rate of the speed of radio waves is approximately 186,000 miles per second.
Rate of the speed of sound waves is approximately 1,100 feet per second.

Radio Waves vs. Sound Waves

Radio waves are the kind of electromagnetic waves that can move or travel whenever there is no medium, on the contrary, sound waves are the kind of mechanical wave that cannot move or travel if there is no medium. Radio waves are diagonal or transverse waves, they may be polarized. While Sound waves are linear or longitudinal waves. They may not be polarized. Radio waves are far faster, typically traveling millions of meters per second, on the other hand, Sound waves are many slower, normally traveling hundreds of or thousands of meters per second. Some characteristics of radio waves, which are the kind of electromagnetic beam or radiation, are that they hold the longer wavelengths and the shorter frequencies on the electromagnetic range, whereas the characteristics of sound waves contain: Frequency, Waveform or Wavelength, Magnitude, Sound pressure, Sound volume, Speed of sound and Direction. All radio waves are similar, as much as light and x-rays, while all the sound waves are not the same. Radio waves are damned electromagnetic waves( just the same light) with the maximum rate or speed keep achievable, on the other hand, Sound waves are a lot of particles strike one another. Radio waves are utilized for many purposes, while sound waves utilized for sending or transfer sound.

What are Radio Waves?

Radio waves are electromagnetic radiations. These are waves made of electromagnetic fields, which are vibrating at right angles. The power of an electromagnetic wave generates at a direction at right angles to the vibrations in both the electric and magnetic fields. Since the actual vibrations occur at right angles to the direction of wave extension, radio waves are cross or transverse waves. Whereas radio waves are not impulsive, they do not require an environment or medium to travel in; they can travel also in a vacuity. Radio waves travel with a speed of around 300 000 km per second in a vacuity. When radio waves entering into other matter, they slower a bit. Radio waves can be made by nature along with artificially. Native or Naturally happening lightening or tremendous objects make radio waves. Unnaturally developed radio waves applied in TV, radios, wireless and navigational systems. The main object radio waves used for transmission attendants or satellites and mobile phones. As well as communications, radio waves as were utilized in medicine for surgeries, therapy sleep disorder, and MRI. Radio waves exchange the characteristics of electromagnetic waves comprising: reflection, diffraction, refraction, absorption, polarization, speed, wavelength and frequency.

What are Sound Waves?

Sound waves usually connected to the travel of sound. Sound theoretically specified as a mechanical commotion traveling across an elastic medium. The medium is not confined to air but can also contain wood, glass, metal, water, and stone. Sound travels in waves, these are titled sound waves. The more frequent method of traveling contains air. Much like all matter, the air is also composed of particles. These particles are kept in motion and high speed. Sound travels in two kinds of waves: transverse and longitudinal waves. Longitudinal waves are waves which one’s course of vibration is the same as their course of travel. The characteristics of sound waves contain Frequency, Sound pressure, Wavelength, Speed of sound and Direction, Amplitude, Sound intensity. The speed of sound is an essential belonging that identifies the speed at which sound travels. The density of the material determines the speed of sound in a medium. Sound travels across the air at room temperature and pressure at a speed of around 340 m per second. Generally, sound can travel quicker in liquids and also quicker in solids. Higher frequency sounds have short wavelengths and lower frequency sounds have long wavelengths.
