Frequency (N) is the number of oscillations per second, while time period (T) is the time for one complete oscillation. Therefore, they are reciprocals of each other. If the time period is 2 seconds, the frequency is 1/2 = 0.5 Hz. The correct relationship is:

$N = \frac{1}{T}$

Final Answer: $N = \frac{1}{T}$
