How are sound waves and radio waves different?

Answer 1

Hi ,

In Frequency

No, for you can have sound and radio waves of similar frequencies. The difference is that radio is electromagnetic whereas sound is a mechanical compression wave.

Answer 2

They are not the same. A radio wave is a low frequency light wave and sound waves are made by compressions and rarefactions of a medium. A radio wave, say in the AM band is say 700kHz that is 700,000 Hz. The highest frequency soundwaves that humans can hear are around ~20,000. That is to say that even if radio waves were a vibration in the atmosphere, like a sound wave, and not light waves, they would be well beyond the range of human hearing.

Radio waves act as carriers for what is called the intelligence. The two most popular methods to store information on a carrier wave are frequency modulation FM and amplitude modulation AM. The intelligence is whatever data is being transmitted, such as sound. A radio's job is to receive the high frequency carrier wave and recover the information that it's carrying and recreate the sound through a speaker. This is typically done in discrete stages. The goal is to essentially to receive the signal and select it through tuning then to amplify what is a very weak signal, to remove the high frequency carrier components and to amplify the resulting signal to the extent necessary to drive whatever actuator or speaker is being used. A simple radio may have these stages. 1) tuner, 2) radio frequency amplifier, 3) detection, 4) audio amplification and lastly power amplification.

Answer 3

Radio waves are part of the Electromagnetic Spectrum and come from the sun.
