What will most likely happen if a sound wave moves from the air through a solid?

a. it will increase wavelength

b. it will decrease in speed

c. it will increase in speed

d. it will decrease in wavelength

Answer is: c. it will increase in speed.

Sound waves travel faster in more dense material, and the more dense the material the louder the sound is.

Sound travels approximately fifteen times faster through the metal railway tracks than through air.

The speed of sound is faster in solid materials and slower in liquids or gases.

The denser is material, the closer are the molecules to each other and the less time it takes to molecules to pass the sound to each other and sound is faster.

c. it will increase in speed is the correct answer.

Explanation:

Sound waves move faster in more solid substance, and the denser the body the deeper the sound moves. The speed of sound is faster in solid substances and it is slower in fluids or gases. The more solid is material the molecules are very closer to each other and the less time it needs molecules to move. Thus if a sound wave moves from the air through a solid it will increase in speed.
