Radio waves are a type of electromagnetic radiation best-known for their use in communication technologies, such as television, mobile phones and radios. These devices receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves. The radio-frequency spectrum is ...
The main difference between AM and FM radio waves is that AM waves are amplitude modulated while FM waves are frequency modulated. AM waves are older and have a larger range, while FM waves have a smaller range but provide better sound quality. Back when people still used radios (instead of...

Radio waves: what appears to be merely a clock radio is more than the sum of its parts.Soviero, Marcelle M
Ah, another interesting sound is the “tweek.”Tweeks are the result of VLF waves that have traveled a long distance through the waveguides.They produce a chirpy sound because the higher–frequency parts of the wave reach the radio receiver before the lower–frequency parts.The entire wave is ...
Um, today, we'll focus on radio waves, and specifically, very low frequency radio waves. Yes, Tim. Student: Are you going to talk at all about the difference between radio waves and sound waves? Professor: Uh, Ok. That might be a good place to start actually. Sound waves are mechanic...
What are waves produced by?Waves:A wave is a moving vibration. A vibration is anything that moves back and forth, up and down, etc. It can result from the vibration of a material (such as your vocal chords or a pendulum) or electric and magnetic fields (or the vibration of energy)....
What Are Fast Radio Bursts or FRBs and How Do We Find More? What Are Stellar-Mass and Intermediate-Mass Black Holes? What Are Some Objects That Challenge the Definition of Pulsars? What Have We Learned From Neutron Stars Interacting With Their Environment?
Digital audio encodes sound as digital signals for storage and playback, whereas analog audio uses continuous signals that mimic the original sound waves. 1 How do sound waves differ from radio waves? Sound waves are mechanical pressure waves in mediums like air, whereas radio waves are electroma...
