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.
Sound 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.
A 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.
Sound waves are a form of mechanical wave that only travels and forms through a medium while electromagnetic waves does not a medium to travel and form.
EM require no medium.
The difference is that a low wave have long and smooth wave and a high wave has skinny and cramped togetther waves
sound waves are made by amplitudes
sounds waves are longitudinal and mechanical waves
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 through vaccum.
Sound waves are resulted due to vibrations.
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
u figure it out dude
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).
sound are longitudinal waves while water waves are transverse waves
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.
refraction is where the soubd waves bend, reflection is when sound waves bounce off of things and change direction.
Sound wave is is generated by a vibrating object.Whereas, seismic wave is the vibration generated by an earthquake or explosion.
sound waves with frequencies 20 hertz or lower are infrasonic and waves above 20,000hertz are ultra sonic!
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.
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.
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:
