Answer:
v = 34.78 m/s
λ = 10.5 mm = 0.0105 m
f = 3312.4 Hz = 3.312 KHz
Explanation:
The relationship between the wavelength, frequency and velocity of a wave is as follows:
[tex]v = f\lambda[/tex]
where,
v = speed of the wave
f = frequency of the wave
λ = wavelength of the wave
So, in this case we have:
v = 34.78 m/s
λ = 10.5 mm = 0.0105 m
Therefore,
[tex]34.78\ m/s = (f)(0.0105\ m)\\[/tex]
f = 3312.4 Hz = 3.312 KHz
