So far we've seen situations in which Wave 1 and Wave 2 have the same amplitude. But constructive and destructive interference isnot limited to situations in which each wave has the same amplitude. Tap on the Destruct button again. Observe the Wave Sum.Then change the amplitude of Wave 1 to 0.16 m; keep the amplitude of Wave 2 at 0.32 m. This is also an example of destructiveinterference. Observe the Wave Sum.Describe how it is different than a situation in which two waves have the same amplitudeIf the two waves have the same_the wave sum amplitude becomes
