Question

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

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

Answer 1

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

Frequency (f) is defined as number of vibrations per second. However, time period is defined as the time taken to complete one oscillation.

$Frequency=\frac{1}{\text{Time period}}\Rightarrow f=\frac{1}{T}$

Hence, the correct answer is option (c).
