superposition and interference explained

In this video, I go though wave interference / superposition.
I discuss constructive and destructive interference from a 1D perspective.
I use the Grapher program on my Mac, but any graphic app will work

So if energy cannot be created or destroyed, what happens when the two waves traveling in the same direction perfectly destruct one another? As in, where does that energy go, or what is it converted to?

ik im a year late, but I might be able to help someone else if they have the same question and are seeing this. There is energy acting in one direction (i.e. one wave is going up) and the energy of the other wave is travelling in the opposite direction (the other wave is going down) at the same point in space and time, and, assuming the waves are in inverse phase (at a 2π rad or 180° offset, as seen at 4:23 in the video) the energy is just gonna cancel out. It's the same as those resultant force questions from GCSE; you have 4N acting right, and 4N acting left, the resultant force is 0. The energy is still there, one's just cancelling the other out.
