There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.
How are electromagnetic waves different from sound waves?
2) Sound waves are elastic waves and propagate through actual vibrations of constituent particles in the medium it travels though. The EM waves on the other hand are due to oscillating electric and magnetic fields perpendicular mutually and also to the direction of motion.
Why sound is not an electromagnetic wave?
Electromagnetic wave is a by-product of both electric and magnetic field. It does not require presence of any medium and can travel through vacuum. Whereas mechanical waves requires the presence of medium. … That’s why Sound is a mechanical wave and not an Electromagnetic wave.
What are 3 differences between sound waves and electromagnetic waves?
Sound creates pressure variations (waves) in matter, such as air or water, or your eardrum. Conversely, radio waves are electromagnetic waves, like visible light, infrared, ultraviolet, X-rays, and gamma rays. EM waves don’t need a medium in which to propagate; they can travel through a vacuum, such as outer space.
Which is faster sound waves or electromagnetic waves?
Sound travels at approximately 1,100 feet per second (766 miles per hour). Radio waves travel at the speed of light, which is approximately 186,000 miles per second.
Why do sound waves and radio waves have different frequencies?
The sound creates differences in pressure, which triggers the oscillation of the molecules, and one molecule passes the wave onto its neighboring molecules. If there are no molecules (vacuum), there is no wave. Sound cannot be transmitted through a vacuum. … It just has a different frequency than the radio waves.
Is sound considered as an electromagnetic wave?
Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge. … The mechanism of energy transport through a medium involves the absorption and reemission of the wave energy by the atoms of the material.
Do electromagnetic waves make sound?
The waves themselves don’t usually produce sound, but their effect on other objects (particularly ferromagnetic ones) can be audible. This is similar to how speakers work (except they use magnetic fields, not waves).
How are EM waves similar to sound waves?
Explanation: Sound waves are compression waves in air (and in other materials, including things like steel and water). … Electromagnetic waves are transverse, and made up of electric and magnetic fields. They do not require a material to travel in – this is how light from distant stars travels to us through space.
