Correct Answer - Option 4 : 1 ms
Concept:
Frequency (f):
1). The number of waves that pass a given point per second is called frequency.
2). The unit of frequency is vibration per second or Hertz.
Time period (T):
1). The time taken to complete one full oscillation or cycle by the Wave is called the time period.
2). The SI unit of the time period is second (s).
The relationship between time period and frequency is given as:
\(Time \ period \ (T) = \frac{1}{f}\)
Calculation:
Given that:
Frequency (f) = 1000 Hz
\(Time \ period \ (T) = \frac{1}{f}\)
T = 1/1000 = 1 msec
