what is the difference between a sound wave and electromagnetic radiation?

Sound wave is longitudinal wave where as emw is transverse wave

Sound waves are a physical process where the medium they are traveling through (like air) are alternately compressed at the frequency of the sound wave. However, electromagnetic waves are a from of radiation (Photons) that stream out from the source in a wave like pattern. Light, radio, x-rays are all forms of electromagnetic radiation. The determining factor in what the frequency is for electromagnetic radiation is the amount of energy the photons contain. Therefore x-ray are more energetic than radio waves. Examples of electromagnetic (EM) radiation listed in order of thier energy from lower to higher. Infrared (heat), visible light, ultraviolet radiation, radio waves, x-rays, gamma radiation.
One interesting fact about EM radiation is that they exhibit properties of both particles and waves. Sound acts strictly as a wave.Source(s): http://imagine.gsfc.nasa.gov/docs/science/know_l1/... http://www.physicsclassroom.com/Class/sound/U11L1a...

the difference between sound waves and electromagnetic ones is the difference in a wave across a slinky that is a series of compressions and rarefactions( a fancy word for streches) and the wave across a jump rope where it is going up and down
any point along a slinky is moving left and right during the motion of the wave
any point along a jump rope is moving up and down
also sound waves are across air while electromagnetic waves are using different types of spacial media such as photons

Sound wave is formed from vibration of object and also needs medium to travel. It actually travels by transmitting the vibration from one layer to another. EM waves are generated from the interaction of Electric and Magnetic Field. EM wave needs no medium to transmit energy. Sound waves (Acoustic wave you may also say) generally travel a lot slower than electromagnetic waves, but the speed of each is dependent on the characteristics of the medium that it is traveling through. The frequency of Acoustic wave is much lower than that of the EM Waves and as the energy is directly proportional to the frequency, Sound wave can transmit much lower energy and consequently it can't travel far.
