Q. Consider the following statements regarding the speed of sound in solids: - Strong bonds between atoms or molecules in solids contribute to higher sound velocity.
- Close packing of particles in solids enables faster transmission of sound waves.
- Lower elasticity in solids compared to liquids and gases is a factor in higher sound velocity.
- A well-defined and ordered arrangement of particles in solids aids the propagation of sound.
How many of the above statements are correct?
Answer:
Only 3
Notes: Statements 1, 2, and 4 are correct. Sound travels faster in solids due to strong interatomic bonds, close particle packing, and an ordered arrangement. Statement 3 is incorrect—solids have higher, not lower, elasticity than liquids and gases, which further facilitates faster sound propagation. Thus, only three statements are correct.
