What is true about the velocity of sound waves in solids compared to air?

A.) Travels faster in solids because the particles are closer together.

B.) Travels the same speed in all media.

C.) Travels slower in solids because the particles are closer together.

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.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
