Which statement correctly describes sound waves? sound waves do not travel through a medium. sound waves are transverse waves. sound waves are longitudinal waves. sound waves are not considered mechanical waves.

Explanation :

Sound waves are the longitudinal waves. In longitudinal waves, the particles of the wave move parallel to the direction of propagation of waves.

It moves in the form of compression and rarefaction. When the particles are compact in a space the compression occurs while when they far apart form each other rarefaction occurs.

So, the correct option is (b) " Sound waves are longitudinal waves".
