A regular wave train has a wavelength of 10.5mm. If the wave is moving at 34.78m/s what are the wavelength, frequency, and velocity

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
