Relation between frequency and wavelength (3140)

A spring is producing waves of frequency 4 Hz and wavelength 0.5 m. What is its velocity? What will be its wavelength if the frequency is double? What will be its wavelength if frequency is reduced to half?

P.-S.

The wave’s velocity is:

\color[RGB]{2,112,20}{\bm{v = \lambda \cdot \nu}}

v = 0.5\ m\cdot 4\ s^{-1} = \fbox{\color[RGB]{192,0,0}{\bm{2\ \frac{m}{s}}}}


If velocity is constant, when frequency is doubled wavelength must be half. In the same way if frequency is halved, wavelength have to be double.
