When traveling from a solid to air, what would you expect a sound wave to do? a)speed up b) slow down c)stay the same speed d) fluctuate speed

As sound wave travels from solid to air the speed will change

the equation for the speed of wave is given by

So from above we can say that as the elasticity of medium will increase the speed of sound wave will also increase

Since solid medium is more elastic than air so sound will travel faster in solid and gets slower in air.

B) slow down

temp rises, and expansion
