As a longitudinal wave propagates through a medium (like sound through air), the components of the medium (like air molecules)
A)oscillate back and forth in the same direction that the wave propagates.
B) remain at rest. move perpendicular to the wave's direction of motion.
C) travel through space with the wave.

A good definition of a “wave” is a disturbance of a continuous medium that propagates with a fixed shape at constant velocity. (Griffiths, 1999, Introduction to Electrodynamics). Another way of saying this is the medium (e.g. a string, water, or air) will only propagate a wave as long as its shape satisfies the wave equation: d^2 f/dx^2 =1/v^2 . d^2 f/dt^2 a) Show explicitly whether the displacement function f(x,t) = A sin(kx) cos(ωt) will be propagated in a medium as...
