Normal
Modes
•The motions corresponding to these particular values of
ce or μ are called normal modes of oscillation.
•In a system consisting of n layers of different density,
there are n normal modes
corresponding to the n degrees of freedom.
•A continuously stratified fluid corresponding to an
infinite number of layers, and
so there is an infinite set of modes.
