Question

Frequency $\left(v\right)$ and time period $\left(T\right)$ of a sound wave are related as :

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

Answer 1

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

We have the relation,

$v=\frac{1}{T}$

where,

$v$ is the frequency

$T$ is the time period

Then, the product of the frequency anf time period of the sound wave is unity.

$v\times T=\frac{1}{T}\times T=1$
