Question

the frequency of wave is 20 Hz. if the velocity of the wave produced be 340 metre per second find the wavelength of the wave​

Answer 1

Answer:

velocity = frequency × wavelength

Given,

velocity = 340 m/s.

frequency = 20 Hz = > 20/s .

340 = h × 20

= > h = 340/20

= > h = 17 m

Wavelength is 17 m.

Answer 2

Wavelength of the wave will be 17 m

Explanation:

We have give frequency of the wave f = 20 Hz

Velocity produced v = 340 m/sec

We have to find the wavelength ]

Velocity is given by $v=\lambda f$, here $\lambda$ is wavelength and f is frequency

So wavelength will be equal to $\lambda =\frac{v}{f}=\frac{340}{20}=17m$

So wavelength of the sound will be 17 m
