Question

If this entire wave train is 30 meters long what is the wavelength

Answer 1

Answer:

frequency _<. Hz e.) speed 12 cm/s. Wave 7. If this entire wave train is 30 meters long what is the wavelength of this wave? 5. -50. A=l7orlig.

Answer 2

The correct question: If this entire wave train has a speed of 30 meters per minute, what is its wavelength.

The wavelength is 0.08333m.

Given:

The speed of the wave train, V = 30 meters per minute = $\frac{30}{60}$ m/s = 0.5m/s.

From the given figure,

The frequency of the wave train, f = 6 Hz.

To Find:

We have to find the wavelength of the entire wave train.

Solution:

The wavelength is the distance between adjacent crests or troughs in a wave.

The equation connecting wavelength (λ), frequency (f) and speed (V) is as follows.

λ = $\frac{V}{f}$.

On substituting the given values in the above equation, we get,

λ = $\frac{0.5}{6} = 0.08333 m$.

i.e., The wavelength = 0.08333m.

Hence, the wavelength of the entire wave train is 0.08333m.
