WebAug 2, 2024 · A standing wave is a combination of traveling waves going in opposite directions! Likewise, a traveling wave is a combination of standing waves. For example, (8.1.7) cos ( k x − ω t) = cos k x cos ω t + sin k x sin ω t. These relations are important because they show that the relation between k and ω, the dispersion relation, is just the ...
