Two hidden words share this honeycomb. Every hex holds a letter that is either right (it is in one of the words) or wrong.

A grey hex is a wrong letter, already discarded; its number counts the right letters among its neighbours. A flower is a right letter, already matched; the two circled flowers were given at the start. Colour does not mean right: if a letter is right, green goes in word 1, blue in word 2, and brown dotted letters are shared.

Decide each of the 17 closed hexes. The numbers force a single answer, though a few spots need two numbers read together. Then name both words (physics: forces, energy and waves). Spoiler tags, please; I'll post the answer tomorrow.
