Understanding the Concepts

* Frequency (f): The number of complete oscillations (cycles) per second. It's measured in Hertz (Hz).

* Period (T): The time it takes for one complete oscillation. It's measured in seconds.

The Relationship

Frequency and period are inversely proportional:

* f = 1/T or T = 1/f

Calculation

You're given the period (T = 2 seconds). To find the frequency:

* f = 1 / T = 1 / 2 seconds = 0.5 Hz

Answer

The frequency of vibration is 0.5 Hertz. This means the mass at the end of the spring completes half a cycle (oscillation) every second.
