A radio wave travels about 874,000 times as fast as a sound wave,
plus it doesn't need any material to move through, as sound does.
Radio wave travel faster than sound wave. Radio wave is the same as light wave except at different wavelength. It travel at speed of light (3 x 108 m/s). Sound wave travel at only 330 m/s and probably can go up to 3,300 m/s in solid medium which is far slower than the speed of light.
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
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
Air
The sound at 700 Hz vibrates faster, but both sounds travel from place to place through air at the same speed.
Radio waves travel through empty space because they are electromagnetic waves, whereas sound is a wave that must travel through air.
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.
Sound wave do not travel through vaccum as it need medium to travel.
Radio waves are electromagnetic radiation.
The decoder seperates the sound wave from the rest of the radio wave.
In a radio you have the conversion of radio wave energy to sound wave energy.
Any electromagnetic wave in vacuum is about 881,000 times faster than any sound in air.
