Thin film constructive interference equation
WebThis result implies that when the film becomes very thin (d approximately zero), we should expect constructive interference (equivalent to m = 0). That is, just before a soap bubble … WebDestructive interference happens when two waves overlap in such a way that they cancel each other out. Wave interference also depends on the relative phase of the two waves, as this video shows through the …
