Morphology
The noun phrase is transparently compositional: 'periodic' means recurring at regular intervals and 'movement' means motion, so their combination straightforwardly yields 'motion that repeats at regular intervals.' This is a common, cross-linguistically regular compound pattern and a B1 learner who knows both constituents should be able to infer the intended meaning.
Etymology
Periodic movement gives a simple picture: imagine a clock's pendulum or a steady heartbeat moving the same way again and again. Here periodic means 'happening at regular times' and movement is the motion, so the phrase describes motion that repeats in the same amount of time each cycle.
