## Homework Statement

We have the standard standing wave equation, [tex]y=2Acos(2\pi \frac{x}{\lambda})sin(2\pi \frac{t}{T}).[/tex] We must prove that if two x-positions on the wave have an even number of nodes between them, they have a phase difference of 0, whereas in the opposite condition, they have a phase difference of [tex]\pi[/tex].
