Question

Which of the following best describes the relationship between the speed of sound and the type of medium?

A.
Sound travels slower in air because of the large distance between air particles

B.
Sound travels slower in solids because of the small distance between solid particles

C.
Sound travels slower in air because of the small distance between air particles

D.
Sound travels slower in solids because of the large distance between solid particles

Answer 1

Answer:

A.  Sound travels slower in air because of the large distance between air particles

Explanation:

Sound is a mechanical wave that requires a medium for its propagation. Without a medium, sound cannot go through easily or readily. This implies that sound cannot be propagated through a vacuum.

• A vacuum is an empty space without any particles in side.
• Sound waves travel fastest the most in solids because the particles are dense and close to one another.
• The speed of sound in air is the least because of the large distance between air particles.
• Therefore, the speed of sound is medium dependent
