Question

sound Travels at a speed of 339 MS -1 MS if the wavelength is 1.5 CM then find out the frequency of the sound wave

Answer 1

f=v×wavelength
f = 1÷339× 1.5÷100
solve it

Answer 2

Answer:

sound travels at a speed of 339 m/s if the wavelength is 1.5 cm, then the frequency of the sound wave will be $2260\ Hz$

Explanation:

The expression for velocity (v) of a wave in a medium  is given by,

        $v=f \lambda$      

       that is,

       $f = \frac{v}{\lambda}$      ...(1)

where f is the frequency and $\lambda$ is the wavelength of the wave.

In the question, it is given that,

The wavelength of the sound wave  =   $1.5\ cm = 0.15\ m$

The velocity of sound wave  =    $339\ m/s$

Substitute these values into equation(1),

The frequency of sound wave  =    $\frac{339}{0.15} =2260\ Hz$
