Deviations from this type of system causes phonons to have a non-infinite lifetime and is the reason behind thermal expansion in a crystal.
Deviations from this type of system causes phonons to have a non-infinite lifetime and is the reason behind thermal expansion in a crystal. In addition to modeling bond dissociation, the Morse potential also models deviations from this system. These systems are characterized by a potential possessing evenly-spaced energy levels and a ground-state energy of one-half times h-bar times omega. When the second-order linear differential equation that describes these systems is inhomogeneous, they are said to be (*) "driven." The exponential decay of this behavior is referred to as damping. The potential energy of these systems is proportional to the square of the displacement from an equilibrium position. For 10 points, name these systems characterized by periodic sinusoidal movement which include springs and pendulums.
