Question

the time period of a vibrating source producing sound is 0.01s. if the velocity of sound is 340m/s. calculate the wavelenght​

Answer 1

We know that, 1/T=υ and v= υλ

so, 1/0.01=100/s

and given velocity=340 m/s

therefore λ = 340/100

                   = 3.4 m

Answer 2

Given that,

The time period of a vibrating source producing sound, T = 0.01 s

The velocity of sound, v = 340 m/s

To find,

The wavelength of sound

Solution,

If f is the frequency of sound wave, then it is given by :

$f=\dfrac{1}{T}\\\\f=\dfrac{1}{0.01}\\\\f=100\ Hz$

Speed of a wave is :

$v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{340\ m/s}{100\ Hz}\\\\\lambda=3.4\ m$

So, the wavelength of the sound wave is 3.4 meters.
