A wave propagates in an elastic medium at a speed of 2000 m / s and finds the vibration frequency

A wave propagates in an elastic medium at a speed of 2000 m / s and finds the vibration frequency of the points of the medium if the wavelength is 5m.

The oscillation frequency of the points of the medium can be calculated by the formula:

n = υ / λ, where υ is the speed of wave propagation in an elastic medium (υ = 2000 m / s), λ is the wavelength (λ = 5 m).

Let’s calculate the vibration frequency of the points of the medium:

n = υ / λ = 2000/5 = 400 Hz.

Answer: The vibration frequency of points in an elastic medium is 400 Hz.
