Question

What will be the effect on the speed of sound wave if: pressure of medium B decreases​

Answer 1

${ \mathfrak{ \overline{ \underline{ \red{Effect \: of \: content \: speed: }}}}}$

When moderately compacted, the molecules in the center are concentrated, which means that the sound travels faster.

Therefore, the sound speed increases as the rate of density increases.

${ \mathfrak{ \overline{ \underline{ \red{Effect \: of \: pressure \: at \: sound \: speed: }}}}}$

At constant temperature, the gas pressure has no effect on the speed of the sound, because the density will increase, and as the pressure and quantity have equal but contradictory effects on the speed of the sound, and these two contributions cancel out well.
