Solution Summary

A detailed solution is given. The properties of waves are discussed.

Solution Preview

Write the wavefunctions in the following standard form:

Psi = Psi_0 Sin(k x - omega t + phi)

or

Psi = Psi_0 Sin(k x + omega t + phi)

The first expression represents a wave moving in the positive x direction, while the second form ...
