What is the main difference between the acoustic and electromagnetic waves?

Acoustic waves occur as the propagated mechanical vibration of particles in a medium. They cannot travel in a vacuum. Electromagnetic waves consist of an alternating electric and magnetic field that propagates throughout space, including a vacuum. Both acoustic and electromagnetic MMWs are used in medicine.

What are 3 differences between sound waves and electromagnetic waves?

Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.

What are the similarities and differences between sound waves and electromagnetic waves?

Sound waves are longitudinal waves which vibrate parallel to the vibrations but Electromagnetic waves propagate perpendicular to electric and magnetic fields. Sound waves need a material medium to propagate but the Electromagnetic waves does not need a material medium to propagate.

Is acoustic wave electromagnetic?

Acoustic waves are generated by a pulsed electromagnetic wave or a burst at a chosen frequency such that materials can be excited with a broad or narrow frequency range.

How are electromagnetic waves similar to acoustic waves?

Sound waves are similar to electromagnetic waves in the sense that they are both waves, and that they both transit energy only. However, they also have extremely different properties, due to sound waves being a type of mechanical wave.
