- Students are placed into small groups and will use the “One dimensional Oscillator Chain” program to simulate various monatomic chains.
- Each group will experimentally find the frequency of oscillation for several coupled oscillators and compare it to the theoretical period of oscillation.
- For a five coupled oscillator system, students investigate the behavior of different normal modes by recording the initial positions of each atom, the frequency of oscillation, and the wave number at each mode.
- Students will plot the dispersion relation for the five coupled oscillator system and compare the dispersion relation for when $k > \frac{\pi}{a}\,m^{-1}$, where $a$ is the repeat distance between atoms.
