Question

The frequency of a man's voice is $300Hz$. If the velocity of sound waves is $336m{s}^{-1}$, the wavelength of the sound is

• A. $1.12m$
• B. $300\times 336m$
• C. $330/336m$
• D. None of these

Answer 1

The correct option is A $1.12m$

We are given, frequency $f=300Hz$, and velocity $v=336m{s}^{-1}$,

From the relation $v=f\times \lambda$,

$\lambda =v/f=336/300=1.12m$

Option "A" is correct.
