i have a question about sound waves :
we know that the equation of sound wave can be written in the form s=Sm cos(kx-wt)
,but i still don't get the meaning of Sm .I know that in the transverse wave ingeneral , and in particular the string the maximum amplitude is how much the string can go vertically upward ,
so what about the maximum amplitude in sound wave?
PS the defintion of sound wave amplitude is the maximum postion of the element at equilibrium ?
