Root Explanation

Photonuclear → It is formed from "photo-" (from Greek "phōs", meaning light) and "nuclear" (from Latin "nucleus", meaning kernel or core). The word refers to processes involving light and the nucleus of an atom.

Memory Tip

Think of 'light' ('photo-') interacting with the 'core' ('nuclear') of an atom — that's what photonuclear means.
