Question
Chapter 17, Problem 1OQ
To determine
The highest value of speed of sound in solid is due to.
Expert Solution & Answer
Answer to Problem 1OQ
Option (a). The difference in density between solids and gases.
Explanation of Solution
In case of solids the neighboring particles are tightly packed as compared to liquids and gases. Since the particles are so close in solids, when sound passes through solids they collide quickly and take less time to propagate through neighboring particles.
Since particles are tightly packed, the density of solids is greater than that of gas, and greater density is responsible for the higher propagation speed in solids.
Conclusion:
Option (a) is the correct answer. The speed of sound in a medium is highly influenced by the density of the medium.
The difference in the compressibility of solid and gas did not affect much in the speed of the sound in solids and gases. Hence option (b) is less correct.
The speed of the sound in a medium is less affected by the size of the medium. Hence option (c) is less correct.
Since density is predominant than any other factors option (d) is also incorrect.
