Webb11 aug. 2024 · Figure 12.1. Connected with each value of K are two values of ω, as can be seen in the graph. The upper line describes the optical branch, the lower line the acoustical branch. In the optical branch, both types of ions oscillate with opposite phases, in the acoustical branch they oscillate with the same phase.
