What? For a wave to have a "bulge" above the top of the tank means
there is a trough well below the top of the tank. The amount of liquid

I didn't say it did. Anyway,

What did you mean by, "that tank will hold more liquid that it
would if brim full without the wave"???


I've been looking at images on Google,
apparently the single half-wave form is concave in a tank of liquid, not
convex. Maybe that too is possible, I don't know. If it is, then you can add
liquid to what was a brim-fill tank before it overflows once the wave is set
up, which would indicate that a form of storage has been set up.

You are aware that a standing wave still moves up and down, no? So a
trough turns into a crest and vice versa.
