Morphology

theta + wave

This is a straightforward compositional technical term: 'theta' names a particular frequency band and 'wave' denotes an oscillatory pattern, so 'theta wave' naturally means a wave in the theta frequency band (i.e., a type of brainwave). Although domain-specific, the adjective+noun structure is transparent and cross-linguistically parallel, so a B1 learner who knows both constituents could infer the meaning.

Etymology

Theta wave comes from early scientists who named repeating brain patterns with Greek letters. They called a slow, low pattern theta and used wave to show the up-and-down signal, so a theta wave now means the brain rhythm you see when someone is 'relaxed' or 'drowsy'.
