Understanding the Relationship
* Frequency (f): How many wave cycles occur in one second. Measured in Hertz (Hz).
* Period (T): The time it takes for one complete wave cycle to occur. Measured in seconds (s).
The Formula
The relationship between frequency and period is:
f = 1 / T
Calculation
1. Substitute the given period: T = 0.25 seconds
2. Calculate the frequency: f = 1 / 0.25 s = 4 Hz
Answer: The frequency of the wave is 4 Hertz.
