No. They are not. Some differences: Sound is a wave of pressure (mechanical wave). Hence, it requires a medium to propagate. read more
Yes, in the sense that electromagnetism (mediated by photons) are responsible for all the interactions between atoms that produce the compression or shear forces that generate sound waves. read more
Sound waves and electromagnetic waves are two different types of waves that are seen daily. Sound waves are responsible for the travel of sound using a medium, while electromagnetic waves are responsible for the travel of light or radio waves and is a result of changes in the electric and magnetic field. read more
No. Sound waves are not electromagnetic waves. Sound waves are mechanical waves propagated by oscillation of physical material and needs physical medium. Where as electromagnetic waves are generated by oscillation of electrostatic and magnetic fields together and do not need physical medium. read more
Now, since the time of Newton there had been a debate about whether light was a wave---that is, a traveling disturbance in some background medium---or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.Source: quotemaster.org
