Question

The relation between frequency(f) and time period(T) is given by

• A. f = T
• B. f = $\frac{1}{T}$
• C. T = f${}^2$
• D. T = f${}^3$

Answer 1

The correct option is B f = $\frac{1}{T}$

The frequency (f) of a wave is the number of full wave forms 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 time period are reciprocals.
That is, T=1/f.
