The Correct Answer is Option 4 i.e 1/Frequency

CONCEPT:

  • Frequency (ν): The number of waves that pass a given point per second is called frequency.
    • The unit of frequency is vibration per second or Hertz.
  • Time period (T): The time taken to complete one full oscillation or cycle by the Wave is called time period.

    • The SI unit of the time period is second (s).

The relationship between time period and frequency is given as:

Time period (T) = 1/ν 

EXPLANATION:

Hence frequency v and time period T are inversely proportional to each other.

Time period (T) = 1/frequency (ν)

So option 4 is correct.
