Let's select the best explanation for the relationship between the speed of sound and the medium through which it passes.
The speed of sound wave can be said to be how fast a sound wave passes from one particle to another particle through a medium.
• When sound is passed through air, the speed of the sound wave is slower.
,
• When sound travels through solids, the speed of the sound wave is faster.
,
• The speed of sound wave is also fast in liquid when sound passes through a liquid.
The speed of the sound wave is slower in air because air is easily compressible. Sound travels slower in air because the distance between of the distance between the air particles are farther apart(distance between atoms).
Also, the speed of sound wave is faster in solids because the molecules of a solid are closer together.
Therefore, we can say the best explanation from the given list is:
Sound travels faster in solids because of the decreased distance between the solid particles.
ANSWER:
C. Sound travels faster in solids because of the decreased distance between the solid particles
