Explanation:
Travels faster in solids because the particles are closer together.
The reason for the above statement is -
(i) Sound waves travel through the medium (solid, Liquid, and gas), more denser is the medium more is the speed of sound.
(ii) In solid, the particles are arranged very closely and tightly packed therefore the sound waves in solid have the fastest speed or travels fastest in comparison to liquid and gas.
(iii) Slower than solid is the travel of sound waves in liquid than in gas(least dense, particles are far apart.
