Answer:
0ption c)
Step-by-step explanation:
The "Time Period" is the time taken for one complete cycle of vibration to pass a specific point.
As the frequency of a wave increases, the time period of the wave decreases and as the frequency of a wave decreases, the time period of the wave increases.
We know that, T= 1/f (T = Time period, and f = frequency)
So, the answer is, f = 1/0.5 = 2 Hz.
The unit of frequency is Hz (Hertz)
