Question

A 3.2 Hz continuous wave travels on a Slinky. If the wavelength is 0.49 m, what is the speed of waves on the Slinky (in m/s)?

Answer 1

$\lambda = \frac{\upsilon}{\nu}$

$\lambda$ - wavelength, m

$\upsilon$ - speed of the wave, m/s

$\nu$ - frequency of the wave, Hz

$\upsilon = \lambda \cdot \nu$

$\upsilon = 0.49 \cdot 3.2 = 1.568 \; m/s \approx 1.6 \; m/s$

Answer: 1.6 m/s.
