Vibrations,ribe a wave by considering the motion of every individual particle. However, there is much to be gained by becoming familiar with the properties of vibrations of a single particle. We shall consider the case of a particle of mass . attached to one end of a spring of stiffness ., the other end of which is fixed.

Vibrations,dium in which the wave propagates. The medium does, of course, contain many millions of particles and it would be a very ambitious task to try to describe a wave by considering the motion of every individual particle. However, there is much to be gained by becoming familiar with the properties of vi

Wave Motion,n motion. The disturbance set up by flicking the string will travel down the string. During the passage of the disturbance, each particle of the string remains at rest until the disturbance reaches it, at which instant the particle is displaced, returning to its original position once the disturbanc
