Sound WavesĪ sound wave is a mechanical longitudinal wave. ![]() They don’t need a medium to move in this is how light from faraway stars reaches us via space. Radio waves are made from transverse electric and magnetic fields. The radio spectrum is defined as a band of frequencies ranging from 3 kilohertz to 3000 gigahertz. A kilohertz (kHz) is one thousand Hz a megahertz (MHz) is one million Hz, and a gigahertz (GHz) is one billion Hz. The wavelength is the amount of space it takes for a wave to complete one cycle.Īccording to NASA, frequency refers to the number of cycles (or times) a wave repeats in a second. A cycle is the full pattern of a wave before it repeats itself. Radio WavesĪ radio wave is an electromagnetic wave and is the fundamental component of radio communications. So, let’s dig into the following information to clarify what are radio waves and sound waves. On the other hand, sound waves are a type of mechanical wave that cannot. The primary distinction between radio waves and sound waves is that radio waves are a form of electromagnetic wave that can move without a medium. When you use a radio, it receives radio waves, processes them, and changes them into sound waves, which you hear in the form of music or speech. But sound waves travel at a considerably slower speed than radio waves. Both waves have a wavelength, frequency, and velocity and transport energy from one location to another. Which is Better: Radio Waves or Sound Waves?įirst things first, both waves produce sound.The Main Difference Between a Radio Wave and a Sound Wave. ![]()
