Answer 1

Answer:

2.Sound wave propagates because of compression and rarefaction of the particles of the medium. When an object starts vibrating, it creates disturbance in medium. ... The region where particles are come closer to each other is called compression and region where particles go farther to each other is called rarefaction.

3.The speed of sound is highest in solid. The speed of sound depends on the density of the medium through which it is travelling. The higher the density of the medium, the faster is the propagation of sound. Since density of solids is higher than that of liquids and gasees, so sound travels faster in solids.
