Sound waves requires a medium, electromagnetic waves do not.
Sound waves are longitudinal waves, electromagnetic waves are transverse waves.
Sound waves Travels at approx. 330m/s in air, electromagnetic waves travel at approx. 3 x 10^8 m/s.

∙ 14y agoSound waves are longitudinal waves, they travel as compressions and rarefactions, and cannot travel in a vacuum. The speed of sound is a lot less than electromagnetic waves, and it's calculated as v=332m/s + (0.59 x temperature°C).
Electromagnetic waves are transverse waves(crests and troughs), and can travel in a vacuum.
Their speed is 3.00 x 108m/s in a vacuum.

∙ 14y agoA sound wave is a succession of air molecule compression and rarefaction. So the air molecules 'vibrate' between periods of being closer together (compression) and farther apart (rarefaction). When they bounce off of your eardrum, you hear them provided the frequency and intensity are adequate. An EM wave is quite different. To be honest, you'll have to check out the wikipedia page! http:/en.wikipedia.org/wiki/Electromagnetic_radiation It will propagate in a vacuum, whereas a sound wave requires a medium to travel through (like air, water..... the kitchen table.) Light is an EM wave.

The difference between a low amplitude sound wave and a high amplitude sound wave is what?
The difference is that a low wave have long and smooth wave and a high wave has skinny and cramped togetther waves
How are sound waves made?
sound waves are made by amplitudes
Sound waves are waves?
sounds waves are longitudinal and mechanical waves
What is the relationship between the movement of the wave and the movement of the particles of the medium?
The dispersion relationship depends on the medium through which the waves propagate and on the type of waves (for instance electromagnetic, sound or water waves). For sound waves, the denser a medium is, the faster the waves will travel as particles will be closer together and thus energy can be transferred among them at a greater rate.
Sound waves cannot travel on the?
Sound waves cannot travel through vaccum.
What is the difference between sound waves and vibrations?
Sound waves are resulted due to vibrations.
What is the difference between the sound waves and ultrasound?
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
What is the difference between sound waves and earthquake waves?
u figure it out dude
What is the difference between ultrasonic and infrasonic sound waves?
The sound waves which are below the audible sound are called infrasonics(<20Hz) and The sound waves which are above the audible sound are called ultrasonics(>20KHz).
What is the difference between waves made by the breeze and waves made by a speedboat?
sound are longitudinal waves while water waves are transverse waves
Do microwaves work with sound waves at all?
Microwaves and sound waves are similar because they are electromagnetic waves. The main difference between the two types of waves is the length of the wave. Sound waves are longer than microwaves.
What is the difference between Sound Reflection and Sound Refraction?
refraction is where the soubd waves bend, reflection is when sound waves bounce off of things and change direction.
A difference between sound waves and seismic waves?
Sound wave is is generated by a vibrating object.Whereas, seismic wave is the vibration generated by an earthquake or explosion.
What is the difference between ultra sonic and infrasonic sound?
sound waves with frequencies 20 hertz or lower are infrasonic and waves above 20,000hertz are ultra sonic!
What waves are in sound waves?
Sound waves in water are essentially the same as sound waves in air; they consist of a sequence of slight compressions of the water between non-compressed water, much as sound in air consists of denser sections of air in between less dense air. The main difference is that sound travels faster in water. The denser medium conducts sound better.
What does the loudness of sound depends on?
the loudness of sound depends on the amplitude of the waves that compose it, i.e. the difference in pressure between the crest and the trough of the wave.
What are coherent waves?
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
