What is the frequency of the sound wave?

Answer 1

QUESTION:-

Maria determines that the wavelength of a sound wave is 2.50 meters and that the wave is traveling at 340 m/s.What is the frequency of the sound wave?

GIVEN:-

$\lambda$ = 2.50m

V = 340m/s

$\mu$ = ?

FORMULA:-

V = $\mu$ ×$\lambda$

NOW,

$\rightarrow$ 340 = $\mu$ × 2.50

$\rightarrow$ $\mu$ = 340 / 2.50

$\rightarrow$ $\mu$ =136hz.

SO, the frequency of the sound wave is 136hz.
