Question

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

• A. f = T
• B. f = 1/T
• C. f² = T
• D. f³ = T

Answer 1

The correct option is B

f = 1/T

Frequency

The number of cycles finished in one second is called frequency$\left(f\right)$.

Time period

The time taken to finish one vibration is referred to as the time period$\left(T\right)$.

Frequency$\left(f\right)$ and time period$\left(T\right)$ are inversely proportional.

Frequency ($f$) and time period ($T$) are reciprocals.

So$f=\frac{1}{T}$

Hence, option B is the answer.
