If frequency decreases while wavelength stays fixed, what happens to the period?

Explanation:
The period and frequency are reciprocal: T = 1/f. So when frequency decreases, the period grows longer. With wavelength fixed, the wave speed v = fλ will also drop as f drops (since λ is constant). A slower wave means it takes more time for one cycle to pass a point, which again means a longer period. In short, lowering frequency while keeping wavelength fixed increases the period.
