Question

The mechanical waves (sound waves ) in gas are

Answer 1

Explanation:

Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves.

Answer 2

Answer:

A medium of gas normal to sound contains neutral atoms and molecules which conduct the transmission of sound waves through the gas. Sound waves which propagate in a gas contain lighter molecules, and fewer of them per volume, than in liquids or solids.
