Answer 2

Answer:

• Sound is a form of energy which produces a sensation of hearing in our ears.
• Sound is produced by a vibrating body. Sound waves need a material medium to propagate from one place to other place. So they are mechanical waves.
• Sound wave travels through medium in the form of compressions and rarefactions.
• The particles of medium move to and fro along the direction of propagation. Therefore sound waves are longitudinal waves.
• Sound waves dont travel through vaccum.
