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.
What is the difference between an em wave and a sound wave?
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.
What does the e stand for in EM waves?
EM waves stand for Electromagnetic waves.
Compare and contrast light and sound waves?
Comparison:Both light waves and sound waves are a method of energy transfer.Both types of waves change their speed when traveling through various media.Contrast:Light waves are electromagnetic waves, and do not require a medium (matter) in order to travel. Sound waves MUST have a medium in order to travelThe speed of a light wave is faster than the speed of a sound wave.Light waves are transverse waves. Sound waves are longitudinal waves.
Are em waves longitudinal are transverse?
EM waves are both Transverse and Longitudinal.

What does E in EM wave stand for?
EM waves stand for Electromagnetic waves.
Why antenna is a sensor of EM waves?
The transmitter sends out EM waves. EM waves are a carrier of energy and are produced by oscillating charges - usually caused by connecting metal to AC power supply. The waves travel through a medium and transfers its energy to the antenna which is basically a metal rod. The energy causes charges in the metal to oscillate at a certain frequency, controlled at the transmitting end. The charges oscillate to produce corresponding EM waves which can be detected/read as signals and turned into sound energy etc...
What does the e stand for in EM waves?
EM waves stand for Electromagnetic waves.
Is the sound from an electric guitar a sound or electromagnetic wave?
sound waves are all around us. the electric guitar will make/reflect sound waves just as it sits in the corner. sound waves is what sound is only that sound waves is the more scientific way of saying it.
Which EM waves have the longest wavelenghts?
Radio waves

Can you convert sound waves to light waves or viseversa?
Yes, this happens all the time with communications. As radio and microwaves from mobile phones and radios are a form of the EM spectrum, which are converted into sound waves in the form of a person speaking or a song playing.
Are em waves longitudinal are transverse?
EM waves are both Transverse and Longitudinal.
What type of em waves do cell phones depend on?
Cell Phones depend on The EM Radio Waves to Work. By: And
What is the difference between sound waves and electromagetic?
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.
