Question

Frequency (v) and time period (T) are related as

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

Answer 1

The correct option is A $v\times T=1$

The frequency is defined as : No of waves in per unit time or time taken by one wave, i-e. Mathematically,

Frequency $=$ Number of waves/ Time taken

$\Rightarrow \nu =\frac{1}{T}\Rightarrow \nu T=1$

$\therefore$ This implie the product of frequency & Time period of wave is unit and hence option (A) is correct answer.
