Answer:
The frequency (f) of a wave is the number of full waveforms generated per second. This is the same as the number of repetitions per second or the number of oscillations per second.
Time Period (T) is the number of seconds per waveform or the number of seconds per oscillation. It is clear that frequency and period are reciprocals.
In this case, A tuning fork's tongs vibrate 250 times in 2.0 s.
That is, the frequency is given as f=2250=125Hz.
Time period = f1=1251=8×10−3s.
Hence, the frequency is 125 Hz and the time period is 8×10−3s seconds.
