Electromagnetic wave is transverse in nature whereas sound waves are longitudinal
Electromagnetic waves are not mechanical waves. This means that it does not need any material medium to pass through. Even through free space ie vacuum em wave can traverse. But sound waves are mechanical and hence a material medium is a must.
Electromagnetic waves has electrical and magnetic energy. Sound waves have mechanical energy. Human eyes see the visible part of electromagnetic waves. Human ears hear the audible part of sound waves.
The speed of light in vacuum is 3 x 108 m/s which is incredible. According to theory of relativity, light speed is invariant with respect to the different frames of reference.
But sound speed will be some 330 m/s ie very very low compared to that of light. Sound speed is relative one and it is not an invariant. It depends on the movement of the observer.

Is a EM wave a sound wave?
No, electromagnetic (EM) waves are different from sound waves. EM waves are vibrations of electric and magnetic fields that do not need a medium to travel through, while sound waves are mechanical vibrations that require a medium, such as air or water, to propagate.
Is sound a type of electromagnetic wave?
No, sound is not a type of electromagnetic wave. Sound is actually a mechanical wave that requires a medium (such as air, water, or solids) to travel through, while electromagnetic waves like light do not require a medium and can travel through a vacuum.
Is sound an example of an electromagnetic wave?
No. Sound is a longitudinal wave consisting of mechanical vibrations travelling through matter (solid , liquid, gas, etc). An electromagnetic wave (light) is, classically, a transversely oscillating electric and magnetic field and requires no medium in order to travel.
How is the frequency of an ME wave related to its energy?
The frequency of an electromagnetic (EM) wave is directly proportional to its energy. This means that as the frequency of the EM wave increases, so does its energy. Conversely, a decrease in frequency leads to a decrease in energy of the EM wave.
How is the energy of an em wave determined?
The energy of an electromagnetic (EM) wave is determined by its frequency and amplitude. The higher the frequency, the higher the energy of the wave. Additionally, the amplitude of the wave also plays a role in its energy content.
Why isn't sound a part of the em spectrum?
Sound is a mechanical wave, not an electromagnetic wave.
Is a EM wave a sound wave?
No, electromagnetic (EM) waves are different from sound waves. EM waves are vibrations of electric and magnetic fields that do not need a medium to travel through, while sound waves are mechanical vibrations that require a medium, such as air or water, to propagate.
How is sound wave different from an EM wave?
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.
What is the relationship between various em waves?
wave

When you squeeze together the coils of a spring and release them what type of wave are you creating?
longitudinal. this is like a sound/pressure wave or how automotive traffic flows. the other type of wave is a transverse wave which describes propagation of EM radiation.
How em wave are generated from photon?
em wave is generated by photons which emitter the energy in the form of light
How is the frequency of an ME wave related to its energy?
The frequency of an electromagnetic (EM) wave is directly proportional to its energy. This means that as the frequency of the EM wave increases, so does its energy. Conversely, a decrease in frequency leads to a decrease in energy of the EM wave.
What is the relationship between the directions of the electric and magnetics fields on an EM wave?
They're perpendicular to each other, and both of them are perpendicular to the direction in which the wave is traveling.
What kind of EM wave has the lowest energy?
radio wave
