Question

A sound has a frequency of 50Hz and a wavelength of 10m. What is the speed of sound?​

Answer 1

Answer:

6.84 m

Explanation:

The wavelength of a sound wave is 6.84 meters.

Explanation:

Given that,

Frequency of the sound wave, f = 50 Hz

To find,

mThe wavelength of sound wave.

Solution,

The speed of sound wave is given by the relation as follows :

v=f\times \lambdav=f×λ

\lambda=\dfrac{v}{f}λ=fv

\lambda=\dfrac{342\ m/s}{50\ Hz}λ=50 Hz342 m/s

\lambda=6.84\ mλ=6.84 m

So, the wavelength of a sound wave is 6.84 meters.

Answer 2

answer is=6.84meter

Explanation:

the speed of sound wave is given by the realation as flow

v=f/time\/ambda=f×y
