Explanation:

Step1: Define period of a wave

The period $T$ is the time for one full wave cycle, and it is inversely related to frequency $f$: $T = \frac{1}{f}$. Fewer cycles over the same time mean a larger period.

Step2: Compare wave cycles in cases

Count visible cycles: Case A has ~7 full cycles; Case B has ~4 full cycles, over the same time frame.

Step3: Relate cycles to period

Since Case B has fewer cycles, its frequency is lower, so its period is greater.

Answer:

Case B
