what is the speed of waves on the Slinky (in m/s)?

Question

A 5.2 Hz continuous wave travels on a Slinky. If the wavelength is 0.61 m, what is the speed of waves on the Slinky (in m/s)?

Answer 1

First, the equation being used is:

f = v / l

Where

f = frequency = 5.2 [Hz]

v = velocity = unknown

l = wavelength = .61 [m]

Rearrange for the unknown:

v = f * I

v = 5.2 [1/s] * .61 [m]
